Configuring IPv6 in Windows 2008 servers

Hello experts,

We have three servers running Windows 2008 R2 SP1 in our organization (two DCs and one Exchange 2010). All of them are in the same subnet, they have these IPv4 & IPv6 addresses:

DC1:                  192.168.1.49/24
DNSv4:              192.168.1.50 / 192.168.1.49
IPv6:                   Auto
DNSv6:              ::1

DC2:                  192.168.1.50/24
DNSv4:              192.168.1.49 / 192.168.1.50
IPv6:                   Auto
DNSv6:              ::1

Exchange:         192.168.1.55/24
DNSv4:              192.168.1.50 / 192.168.1.49
IPv6:                   Auto
DNSv6:               Auto

I want to assign IPv6 static addresses to servers instead of those dynamic ones.

Are there private addresses in IPv6 equivalent to 192.168.x.x in IPv4?

Auto is the best way to this will auto generate the IPv6 addresses.

Mistake can happen when configuring manually but here you go.

What about DNS servers? How to tell computers where to go for DNS queries?

DNS will auto configure to point to itself for a DC.

Are you sure the link is working for me?

What about Exchange server and other computers?

Allow Exchange to use the IPv4 for DNS

The automatic addresses should be link local unless the machines receive a network advertisement from a router.
link local addresses being with fe80:: and end with an address that is based on the mac address (unless privacy is turned on, in which case it will just use a random number)

If you want static IPv6 addresses then perhaps the correct question to ask is "How do I turn off ipv6 privacy addressing?"

see these commands:-
netsh interface ipv6 set privacy enabled
netsh interface ipv6 set privacy disabled

IPv6 addresses based on the mac address will have FF:FE in the middle.
