Step 9. As with IPv4, you can configure additional IP addresses if you are not using DHCP. Click Add and type the required IP address into the dialog box that appears.
Step 10. As with IPv4, if your network segment is connected to more than one router, configure additional gateway addresses in the Default Gateways section by clicking the Add button.
Step 11. When finished, click OK until you're returned to the Network Connections dialog box.
Tip
You can also use the netsh.exe tool with the interface IPv6 subcommand to configure IPv6 from the command line. For example, the netsh interface IPv6 set address "local area connection 2" fec0:0:0:ffee::3 sets the IPv6
address of the second local area connection to the specified address. For more information, refer to “IPv6 Configuration Information with the Netsh.exe Tool” at http://technet.microsoft.com/en-us/library/bb726952.aspx#EBAA.
Configuring Network Locations
A network location defines a set of conditions contained within a network profile that govern whether computers on the network can view your computer and resources such as files, folders, and printers to which it is connected. Microsoft makes available network profiles corresponding to private and public network locations that are configured by default to
enhance the security of your computer when connected to a public network such as a Wi-Fi hotspot.
Setting Up New Network Connections
The Network and Sharing Center enables you to set up new networking
connections. Click Set Up a New Connection or Network (refer to Figure 6- 5) to display the Set Up a Connection or Network Wizard shown in Figure 6- 11. (Note that this dialog box may not display all these options; the options vary according to the networking hardware attached to your computer.)
Figure 6-11. Set Up a Connection or Network Wizard Offering Several Options for Connecting Your Computer to Networks
Select from the following options and then click Next:
• Connect to the Internet: Detects any type of device (such as a cable or DSL broadband connection) and enables you to enter the username and password provided by your ISP, as shown in Figure 6-12. You can also enter a connection name that helps you to identify this connection later. If you want to enable other users on the computer to connect, select Allow Other People to Use This Connection.
Figure 6-12. Entering Username and Password to Connect to the Internet
• Set Up a New Network: Searches for the wireless router or access point you want to configure and then attempts to configure this device for you.
Although the wizard states that it might take up to 90 seconds to display unconfigured devices, this process can take considerably longer.
• Manually Connect to a Wireless Network: Enables you to enter the wireless network information required for connecting to the network. We discuss wireless networking in Chapter 11, “Configuring and Securing Mobile Devices.”
• Connect to a Workplace: Enables you to connect by means of a virtual private network (VPN) connection across the Internet or to dial directly to the workplace network using a phone line without using the Internet. We discuss VPN connections in Chapter 15, "Configuring Remote Access."
• Set Up a Wireless Ad Hoc (Computer-to-Computer) Network: Enables you to connect directly to another wireless-enabled computer without the need for a wireless access point. If you do set up a connection of this type, you are disconnected from other wireless networks.
Connecting to Existing Networks
You can manage your network connections using the Network & Internet settings page. From the Action Center, select the Network icon and then click Network Settings. This displays the settings for your current
connections, as shown in Figure 6-13.
Figure 6-13. Network & Internet Settings Page to Manage Your Connections
When you open this settings page, or click the Network icon in Action Center, you are informed which network you are connected to and which networks are available. Select a desired network and then click Connect. To disconnect from a network, select it and then click Disconnect.
These operations apply only to dial-up and Wi-Fi connections. To disconnect from a wired or Ethernet connection, access the Network Connections screen, select the device, and then select Disable This Network Device.
(e)Setting Up Network Sharing and Discovery
You can access additional sharing and network discovery options from the Network & Internet Settings page. Click the Change Advanced Sharing Settings, found in the Related Settings section of the device you are
connected to. As shown in Figure 6-14, the Advanced Sharing Settings dialog box enables you to configure the additional networking options provided in the list that follows. (Available options depend on the profile you're using, either Private, Guest or Public, Domain, or All Networks.)
Figure 6-14. Advanced Sharing Settings Enabling You to Configure Sharing Options for Different Network Profiles
• Network Discovery: Enables your computers to see other network
computers and devices and enables these machines to access your computer.
To ensure that all network devices are detected and configured, ensure that the Turn On Automatic Setup of Network Connected Devices option is selected. (This option is selected by default.)
• File and Printer Sharing and Public Folder Sharing: These options enable you to share files and printers on your computer that will be visible to other computers on the network. We discuss these options in Chapter 14,
"Configuring File and Folder Access."
• Media Streaming: Enables machines on the network to access shared photos, videos, and music stored on your computer. Enables your computer to locate these types of shared information on other network computers.
• File Sharing Connections: Enables you to select the strength of encryption used for protecting file sharing connections with other machines on the
network. By default, file sharing is enabled for machines that use 40- or 56- bit encryption, but you can choose to increase security by selecting 128-bit encryption. However, devices that do not support 128-bit encryption will be unable to access resources on your computer.
• Password Protected Sharing: Requires users attempting to access shared resources on your computer to have a user account with a password. Turn this option off if you want to enable users without a password to have access.
• HomeGroup Connections: Enables you to determine whether Windows
will utilize simple homegroup-based sharing or use the classic type of file sharing model employed by Windows versions prior to Windows 7. More information is provided in Chapter 14.
Tip
You can configure sharing options for up to four network profiles:
1. Private
2. Guest or Public
3. Domain (on a domain-joined computer) 4. All Networks
This enables you to maintain these network profiles when switching between different network types, so that when you connect to a public network, you can select the All Networks option to apply more restrictive sharing options automatically.
Using Internet Connection Sharing to Share Your Internet Connection
Quite often, it is not feasible for a small office or a home user to install a high-speed dedicated link to the Internet (such as a T1 line) or have each computer dial up to an ISP. Nowadays, home users can utilize a dedicated broadband link, such as a reasonably priced cable or DSL link.
One of the growing trends for small office or home networks is to share an Internet connection with all the members of the network. Windows 10
contains a feature called Internet Connection Sharing (ICS), which enables a small office or home network to use one computer on the network as the router to the Internet.
Windows 10's ICS components consist of the following:
• Auto-dial: A method of establishing the Internet connection when
attempting to access Internet resources on a computer that does not host the Internet connection.
• DHCP Allocator: A simplified DHCP service that assigns IP addresses from the address range of 192.168.0.2–192.168.0.254, with a mask of 255.255.255.0 and default gateway of 192.168.0.1.
• DNS Proxy: Forwards DNS requests to the DNS server and forwards the DNS replies back to the clients.
• Network Address Translation (NAT): Maps the range of private Class C IPv4 addresses (192.168.0.1–192.168.0.254) to the public IP address, which is assigned by the ISP. NAT is a specification in TCP/IP that tracks the
source private IP addresses and outbound public IP address(es), reformatting the IP address data in the header dynamically so that the source requests reach the public resources, and the public servers can reply to the correct source-requesting clients.
Note
NAT runs on a server or router and is capable of translating multiple external IP addresses to internal private IP addresses used on client computers. The NAT server/router can also be configured to provide DHCP services to the client computers. For more information on NAT, refer to the “Network Address Translation (NAT) FAQ” at
www.cisco.com/c/en/us/support/docs/ip/network-address-translation- nat/26704-nat-faq-00.html.
You can use ICS to share any type of Internet connection, although it must be a connection that is enabled for all users on the PC dial-up for sharing to be effective. To enable ICS, you need to make sure that the Internet-connected computer has been configured with connections for a modem and a network adapter. If you are using broadband, you need two network adapters: one to connect to the broadband device for the Internet and the other to connect to the network. Use the following procedure at the computer that is connected to
the Internet to set up ICS:
