This article describes the options that must be configured in order for a Windows Server 2008 DHCP using an IPv6 scope server to register on behalf of a client with DNS.
In order for a Windows Server 2008 DHCP server using an IPv6 scope to register on behalf of a client with DNS, there are two options that need to be configured (either at the scope or server level).
1. Option 23 - DNS Recursive Name Server IPV6 Address List
2. Option 24 - Domain Search List
If these options are not configured, you may find that even when a client requests the server register on its behalf, that registration never occurs. Viewing the requests in a network trace will show in the final packet of the DHCP exchange that the server overrides the client request for registration.
Client flag values:
- Flag: 1 (0x1)
MBZ: (00000...) 0
N: (.....0..) DHCPServer SHOULD perform updates (the PTR RR and possibly the AAAA RR based on the 'S' bit)
O: (......0.) the server has not overridden the client's preference for the 'S' bit
S: (.......1) SHOULD perform the AAAA RR (FQDN to address) DNS updates
- Flag: 6 (0x6)
MBZ: (00000...) 0
N: (.....1..) DHCPServer SHOULD NOT perform the any DNS updates
O: (......1.) the server has overridden the client's preference for the 'S' bit
S: (.......0) SHOULD NOT perform the AAAA RR (FQDN to address) DNS updates
