Define Where User Computers Should Receive an Ip in Windows 10

In that sample chapter from Exam Ref 70-697 Configuring Windows Devices, 2nd Edition, search the main networking components of Windows 10 and how to configure apiece of them.

IT is probative to interpret the fundamental principle of networking in Windows 10 to pass the 70-697, Configuring Windows Devices test. Network connectivity is an almost universal assumption in true Windows 10 operation, so understanding how Windows networking works will help you in many areas of the exam. This chapter will cover the basics of principal networking components of Windows 10, along with how to configure each of them.

Skills in this chapter:

• Skill 4.1: Configure Informatics settings

• Acquisition 4.2: Configure network settings

• Skill 4.3: Configure and maintain network security

Skill 4.1: Configure IP settings

The IP address is the most widely used taper of contact for a Windows 10 computer that is connected to the network. A computer's Information processing address unambiguously identifies it on the local net section, and it serves as the operational component for most of the shipway that computers communicate on a network, including appoint resolution and file transferral.

Connect to a network

Networks are groups of computers and different resources. When joined, each resource that is connected (reckoner, network printing machine, server, or other host) must win, or have previously been assigned an unshared address that will define IT on that network. These addresses are unequalled, and you arse't have two hosts on the same network with the similar address. This makes addressing a very important part of configuring and connecting to networks.

Understanding IP destination requirements

Each host on a network must have a specific Net Communications protocol (IP) come up to. This plow, when it's configured as an IPv4 turn to, is a 32-bite phone number that is titled as quartet sets of decimal numbers. For example: 192.168.4.20. Each host is also assigned a subnet mask, which determines which part of the IP address defines the network and which portion defines the host. Together, the IP address and the subnet mask define the network within which a boniface can convey. If the host requires communication outside of the local network segment, a gateway must live specific, which typically represents a network router that can provide network paths to opposite networks and the Internet. The Informatics address, subnet mask and default gateway in collaboration provide the full definition of IP connectivity for a network host. In that location are two ways to get an address to a resource: You can delimit it manually, OR it hindquarters beryllium assigned by a High-energy Host Configuration Protocol (DHCP) server.

When an address can't be assigned this way, Windows will assign its own Information science address exploitation a applied science called Automatic Private IP Addressing (APIPA). APIPA addresses collapse the 169.254.x.x address range.

Understanding mesh terminology

Make a point that you are familiar the pursual terms before continued:

• APIPA This is a link-section (IP) address that is assigned by Windows when no other addressing chemical mechanism behind be found. This enables the host to function on the local anesthetic network segment. Routers do not forward packets from these kinds of addresses.

• Default gateway This hardware or software device lets hosts connect to other networks. Often that network is the Internet, but information technology could likewise be another network segment in an enterprise domain.

• DHCP This is a networking communications protocol that dynamically configures IP addresses for hosts on a network. A DHCP server assigns these addresses. These IP addresses are more often than not granted for a specified separation and must be renewed when the interval is leading. If specific static addresses are required for clients, DHCP can be configured to allow reservations for those clients.

• DHCP Compass A DHCP scope is a consecutive order of possible Informatics addresses that can be offered to hosts on a subnet (set forth of a web).

• DNS Sphere Name Service (DNS) is a service that enables users to typecast the name of the host to which they want to connect to instead of its IP computer address. A DNS server resolves the name.

• IPv4 This is an IP address that consists of 32 bits, notated by four 8-bit octets. Information technology has 2 parts: the meshwork ID and the host ID. The network Gem State describes the network, and the host Gem State defines the specific device thereon. IPv4 addresses can be Unicast, Broadcast, or Multicast.

• Subnet mask This 32-scra number, notated by four 8-scra octets that consist of a set of 1s followed by a plant of 0s, is used to delimitate which part of the IPv4 address is the network ID and which part is the host Idaho. The 1s denote the web; the 0s denote the host. The default subnet masks are in the form 255.0.0.0 for Course of study A addresses, 255.255.0.0 for Class B addresses, and 255.255.255.0 for Category C addresses. Translated to binary, 255.0.0.0 looks like this: 11111111 00000000 00000000 00000000.

• IPv6 The gettable IPv4 plow combinations are dwindling, thus the deman for a better option. IPv6 is that option. Instead of a 32-bit space, information technology's a 128-bit space with 16-bit boundaries. This allows for many more addresses. An IPv6 address typically looks the like this: 21DA:D3:0:2F3B:2AA:FF:FE28:9C5A.

Configuring IP settings

You can configure Information processing settings on a Windows 10 computer by accessing the Properties page for the network arranger. To open the Properties foliate, perform the following steps:

1. From the desktop, right-click the Start button, then click Network Connections.

2. In Settings, dog Change Adapter Options.

3. In the Mesh Connections window, shown in Figure 4-1, right-click the appropriate network adapter, and then click Properties.

4. In the Ethernet Properties panel shown in Figure 4-2, blue-ribbon Net Communications protocol Version 4 (Transmission control protocol/IP4), and so get across Properties.

   

   FIGURE 4-2 Configuring a meshwork connection's properties

5. In the Internet Communications protocol Version 4 Properties dialog box shown in Figure 4-3, select the allow contour options and specify addresses, if necessary. You can choose to either obtain the IP address and DNS server addresses mechanically (from a DHCP host), or specify the addresses manually. You moldiness, at a tokenish, cater an IP savoir-faire and a subnet mask.

Conjunctive to a network

The first prison term you tie in to a section network, you are prompted to choose from one of these options:

• No, Get into't Turn On Share-out Or Connect To Devices This option is planned for public networks and tropical spots (libraries, coffee shops). The drug user's computer toilet't be seen or accessed away others, and the user pot't see other computers also accessing the network.

• Yes, Turning On Sharing And Associate To Devices This option is intended for individual, trusty networks (home, puzzle out) and homegroups. Computers pose behind a trusted router and do non connect to the Cyberspace directly.

These two options do non appear when you connect to an Active Directory Domain Services world. However, when they do appear and when you choose an option, settings are configured automatically for electronic network discovery, file and printer sharing, the state of the firewall, apps that send away accept incoming connections, and so on. (Computers configured as Secluded or Domain have network uncovering enabled; Public networks do non.)

Resolving connectivity issues

When a host can't reach a network, that host has connectivity issues. The issue might be isolated to single that device; perhaps the computer's Ethernet cable has come unplugged or the computer's wireless features have been injured. Perchance at that place is an IP address conflict on the network and the user's IP address of necessity to represent released and renewed. A great deal, using the troubleshooting tools in the Network And Sharing Center can queer the problem and propose a solution. If the come forth isn't isolated though, you cause larger problems. A mesh host, gateway, or other necessary resourcefulness might be down, a mesh segment or physical backbone mightiness comprise damaged, or thither could be an issue that is caused by the Internet service provider (ISP), cloud services, or other technologies that are tabu of your control.

NETWORK AND Unselfish CENTER

The Web And Sharing Center enables you to view the status of your active networks. If there's a problem, you can click Troubleshoot Problems to see if the Network And Sharing Center can purpose IT. It can be single-minded by releasing and reviving the IP address, resetting adapter settings, or discovery a acicular problem such as a disconnected Ethernet cable (which you can then reconnect).

If a problem exists, simply can't be resolved automatically, you can prefer from a list of troubleshooting options that include: resolution problems connecting to websites, accessing shared folders, finding computers or files in a homegroup, finding and repair problems with wireless adapters, and troubleshooting incoming connections. When you select any option and start the trouble shooter, IT generally finds the job and performs the repair operating theater prompts you to authorize the repair. It might besides require you to do something first, like insert an ethernet cable system into the ethernet larboard on the computer.

COMMAND-Rail line TOOLS

When the Network And Communion Center and the Action Center commode't help resolve a connectivity trouble, it's expected a to a greater extent complex issue. Perhaps a domain's (or mesh segment's) gateway is offline or a router failed. Perhaps the DNS server isn't available or has been incorrectly configured on the host, or the unique, corporate, IP address of the computer has been changed to an APIPA direct because of a currently dissonant mesh yield.

When these kinds of problems survive, you potty enjoyment command-line tools to resolve them. Here are some of the tools you posterior use:

• Ping This tool verifies IP-level connectivity to another TCP/IP computer. To do this, it sends Internet Control Message Protocol (ICMP) Echo Request messages to the recipient. The receipt of these messages is displayed, on with round-trip times, if the connection is successful. Ping is the primary command victimised to troubleshoot connectivity, reachability, and name resolution.

• Ipconfig and Ipconfig /altogether This displays all current TCP/Informatics network configuration values. It can as wel refresh DHCP and DNS settings. Used without the /all parameter, Ipconfig displays IPv4 and IPv6 addresses, the subnet mask, and the default gateway for all adapters installed happening the host. Common parameters are /outlet, /renew, and /flushdns.

• Tracert This tool determines the path affected to a destination and shows information close to each hop a packet takes to make where it's going. A hop is a pass through and through a router. You tail use this information to see where the transmission fails.

• Netstat This displays a list of active Transmission control protocol connections and the ports on which the computer is listening. Information technology as wel displays Ethernet statistics, the IP routing table, and IPv4 and IPv6 statistics.

• Netsh This enables you to reach changes to the network configuration of the current electronic computer at the command line.

• Nslookup This tool around displays information that you can use to diagnose problems with DNS.

Configure discover resolution

Computers are depicted away their singular IP address, and you can pass on with them victimisation that address if you like. One way to commune with an IP address is to exercise so at a command line. For example, you can character something like Ping River 192.168.4.5 to troubleshoot connectivity to another host on a local area network segment. Communicating this way however, is cumbersome.

DNS enables users to character names rather of numbers; this appendage is called constitute resolution. DNS servers lay in information about the names and addresses of Internet computers, and the lists they conserve are distributed among thousands of DNS servers available on the Internet, which are placed all over the world. The name answer call for is forwarded to one of these servers. If the name can't glucinium resolved waiter, IT's passed to another waiter and another, until it is resolved.

In many cases, your DHCP server will provide DNS server addresses for your client computers to use for name resolution. This occurs if Obtain DNS Server Address Automatically is selected. You fanny also manually configure a Host to use a specific DNS server in the connecter's Properties panel (shown in Figure 4-3). On a domain with a unique DNS server that the host is obligatory to use, this is necessary. It might too be inevitable in a virtual private meshing (VPN) or in a virtual machine.

Depending connected the configuration, Windows 10 resolves emcee names by performing the undermentioned actions:

1. Checking whether the legion discover is the same as the local Host describ.

2. Searching the DNS resolver cache, which is inhabited from the local Hosts data file.

3. Sending a DNS request to its configured DNS servers.

Troubleshooting name resolution

The primary tools for troubleshooting host name resolution are IPConfig and NSLookup, and their Windows PowerShell equivalents Get-NetIPAddress, Get-NetIPv4Protocol, and Resolve-dnsname.

If you cannot connect to a remote host, and if you defendant a name resolution problem, you can troubleshoot name declaration by using the following function:

1. Unfastened an el prompt, so clear the DNS resolver cache by typing the succeeding command:

                 IPConfig /flushdns            

   Or, you can use the Windows PowerShell cmdlet Clear-DnsClientCache.

2. Attempt to verify connectivity to a remote host by using its IP address. This helps you identify whether the issue is due to gens resolution. You can use up the Ping command or the Test-Joining Windows PowerShell cmdlet. If the Ping command succeeds with the Informatics address, only fails aside the master of ceremonies name, the problem is with cite resolution.

3. Attempt to verify connectivity to the remote host by its host refer aside using the fully-eligible domain epithet (FQDN) followed by a period. For exemplar, type the following command at a Windows PowerShell prompt:

                 Test-connection LON-cl1.adatum.com            

   You can also use the ping overlook.

4. If the test is successful, the problem is likely unrelated to name resolution.

5. If the exam is unsuccessful, edit the C:\Windows\System32\Drivers\Etc\hosts.txt text file, and then add the appropriate entree to the end of the file. For good example, add this line and then save the file:

                 172.16.0.51       LON-cl1.adatum.com            

6. Do the test-by-host-diagnose procedure once more. The name resolution should straightaway be successful.

7. Examine the DNS resolver cache to verify that the name resolved aright. To examine the DNS resolver cache, eccentric the next statement at a command prompt:

                 IPConfig /displaydns            

   You arse also use the Windows PowerShell cmdlet Perplex-DnsClientCache.

8. Remove the entry that you added to the hosts file, and so clear the resolver cache once Thomas More. At the command motivate, type the following command, and then examine the contents of the filename.txt filing cabinet to identify the failing stage in name answer:

                 NSLookup.exe –d2 LON-cl1.adatum.com > computer filename.txt            

   The Windows PowerShell equivalent bidding is:

                 Declaration-dnsname lon-cl1.adatum.com > filename.txt            

Configure electronic network locations

The first time that you link a computer to a network, you must select whether you trust the network. This sets appropriate firewall and security measur settings automatically. When you relate to networks in contrasting locations, you can see to it that your computer is set to an appropriate security level at all times by choosing a electronic network location.

Windows 10 uses network placement awareness to uniquely identify networks to which a computer is attached. Network location awareness collects entropy from networks, including IP address and media approach curb (MAC) address information from main meshwork components, like routers and gateways, to identify a special network.

There are three network fix types:

• Area networks These are work networks that attach to a field. Use this option for some network that allows communicating with a domain controller. Network discovery is on by default, and you cannot create or joint a homegroup.

• Private networks These are networks at home or work where you know and commi the people and devices on the network. When you select home operating room shape (private) networks, this turns on network discovery. Computers on a family electronic network can belong to a homegroup.

• Guest or public networks These are networks publicly places. This location keeps the computer from organism visible to other computers. When you superior the Public lieu web location, homegroup is not available and network discovery is inverted off.

The Exoteric networks placement blocks certain programs and services from running, which protects a computer from unauthorized access. If you connect to a Public network and Windows Firewall is along, some programs or services might ask you to allow them to pass on through and through the firewall so that they can work decent.

To make changes to the network location, if that location is a homegroup, you can run the Homegroup Troubleshooter. This might ne'er happen in a homegroup, but it's worth noting that the Homegroup Troubleshooter is an option. If the location is a local network in a workgroup, you can micturate changes in the Settings app A follows:

1. In the Settings app, clink Network &A; Internet.

2. On the Network &adenosine monophosphate; Net page shown in Figure 4-4, click Ethernet, and and then click the adapter for which you'd like to configure the net locating (Ethernet, in that case).

3. On the Network foliate, subordinate Make this PC discoverable heading, shown in Figure 4-5, change the toggle switch to Off (DO not recover devices, which is recommended for a public network location) or On (see devices, which is suggested for a private network positioning). When you choose Off, the meshing location profile is Populace, and when you choose On, the network location visibility is changed to One-on-one. You can verify this change by clicking Sharing options on the Status tab.
