Is anyone having success with DHCPv6 yet?  I'm curious to hear how people are dealing with the lack of DHCPv6 redundancy (at least with Bluecat) and DHCPv6 DDNS update issues.  It seems that in my deployment, v6 takes precedence over v4 and will not allow a dual stack client to update DDNS for both v6 and v4.  I'm thinking of adding another DNS zone that will handle DDNS updates from the v6 clients, but am not sure if that would be the correct path.

Thank you

These are problems generic to DHCPv6 and not specific to Bluecat. If you want the same DNS hostname to be updated with a client's DHCPv4 'A' record and DHCPv6 'AAAA' record, you can use RFC 4361 if you can find client implementations that are compliant...good luck. Any other possible soultions would have to be custom back-end systems that somehow tie DHCPv4 and DHCPv6 leases together as the same host, and then performs the DDNS update on behalf of the host. You can use RFC 6939 support on your routers/relay agents to help with this, but again, good luck finding support for that yet. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
Hello,

At UNH we run DHCPv6 server on one Infoblox appliance and DDNS (both forward & reverse) for the IPv6 pools using a sub-domain of 'ac.unh.edu'.  Currenlty using a single Redhat server for dhcp6-relay from client network to the DHCPv6 server.

IPv4 provisioning for these clients are via a failover pair of Infoblox DHCP servers as fixed-address assignments in the 'unh.edu' domain and do not yet implement DDNS.

So far this has worked for us and has not created problems.

Thank You,

Thanks for the info guys.  Scott, I'm thinking the sub-domain is the route we will be looking at as well.  




Yeah, definitely not the ideal but it is one way to keep moving forward to support IPv6.
Great topic and nice to see interest and effort -thanks!
