IPv4 has the 192.168.*.*, 172.16-31.*, and 10.*.*.* ranges; IPv6 has one range that is enormously bigger than all of those three put together, which can contain 1,329,227,995,784,915,872,903,807,060,280,344,573 devices. The standard is to use a subnet randomly chosen, to minimize conflict. This page has just generated a 16-bit subnet for you, usable for a maximum of 65534 devices:
Using the above 16-bit subnet, the following is the first IP:
and this is the last:
And just as with v4, you will need a subnet mask. The subnet mask for any 16-bit v6 subnet, is:
The reverse DNS zone name, for the above zone, is:
Please note that the GUI of Windows Server 2008 and 2008 R2, support only 64-bit subnets for reverse DNS setup. So to keep subnet size manageably small, we use command line to create the v6 reverse DNS container object, and then add/change using GUI. A command line in Server 2008 and Server 2008 R2, to create the reverse DNS server object for the above v6 subnet, is:
The Windows Server GUI works perfectly well for forward DNS of all sizes as well as NIC configuration, and is therefore recommendable.
