Configuring IPv6

As with IPv4 configurations, with IPv6 you can either set an automated address configuration through DHCPv6 or configure an address manually. The Netsh command gives you the ability to set all parameters but in this article we will focus on configuring the interface using the Internet Protocol Version 6 (TCP/IPv6) GUI from the Network and Sharing Center.

Before proceeding further, I recommend you to log and receive reports about monitored computers. PC Spy Monitor secretly logs all keystrokes, web sites, emails, chats & IMs. Takes screen snapshots at every X seconds like a surveillance camera. Displays exact activities, like MySpace, Facebook, online searches & shopping, file transfers and web-mails. Perfect for catching cheaters, monitoring employees, children and spouse, chat records and websites visited, and even investigating crimes. You  can download this software and take a trial before order to make sure it works for you.

The only advantage of using the GUI over the netsh command is the GUI which makes the job of adding addresses easier for users unfamiliar with the command line interface! In the following procedure we will be setting a static private address that is, an IPv6 address for the local network connection adapter:

  1. Logon to your computer using administrator privileges
  2. Open Network and Sharing Center and click Change adapter settings
  3. Right click the Local area connection and select Properties
  4. From the Local Area Connection Properties window, select Internet Protocol Version 6 (TCP/IP) and click Properties
  5. From the Internet Protocol Version 6 (TCP/IP) Properties window check the Use the following IPv6 address: and type in a static site-local IPv6 address (ex: fec0:0:0:fffe::1)
  6. Click the text box next to Subnet prefix length: and the value 64 appears automatically. Remember, that site-local addresses start with fec0 and their default subnet is 64, although you can change this setting
  7. Click OK and close the Local Area connections Properties and Network and Sharing Center windows
  8. Before using the ping command to test the configuration, you may need to set a firewall rule that allows ICMPv6 traffic. From a command prompt type:
    netsh advfirewall firewall add rule name=”ICMPv6” protocol=icmpv6:any, any dir=in action=allow
  9. Now, from the an elevated command prompt type ping fec0:0:0:fffe::1 to check local connectivity

To set an IP address using the netsh command type:

netsh interface ipv6 set address “local area connection” fec0:0:0:ffee:2
