I am trying to create a new ipv6 DHCP Scope however I do not know what is an acceptable DHCP Scope and Prefix. Can someone please help me with this? I also currently have unknown being listed on nslookup as the server at the moment and it is listing the ipv6 address for the server as the default so I am hoping that doing the above will also fix this error. Any help will be appreciated.I.T. Construct admin@itconstruct.com.au http://itconstruct.com.au

Hi, The prefix is the part of the address that indicates the bits that have fixed values or are the bits of the network identifier. Prefixes for IPv6 routes and subnet identifiers are expressed in the same way as Classless Inter-Domain Routing (CIDR) notation for IPv4. The following articles could be helpful for you to better understanding IPv6 addressing: Expressing IPv6 addresses http://technet.microsoft.com/en-us/library/cc784831(WS.10).aspx Configuring IPv6 prefix addresses http://technet.microsoft.com/en-us/library/dd857387.aspx IPv6 configuration methods http://technet.microsoft.com/en-us/library/cc779656(WS.10).aspx IPv6 address autoconfiguration http://technet.microsoft.com/en-us/library/cc778502(WS.10).aspx Hope it helps.This posting is provided "AS IS" with no warranties, and confers no rights.

I have a similar issue. My DHCP for IPv6 is set, and my reverse lookup zone. My 2 DC's with static IPv6 addresses and NSLOOKUP any client/server and can only ping eachother. Clients cant NSLOOKUP (Server Unknown) or ping, just times out. But they do get assigned the IPv6 IP within the scope...
