It's been a while since I worked with IPV6 and I am now once again

of holes had now been plugged. What is the accepted way in IPV6 land to
dish out IPV6 DNS server addresses (am I correct in saying that if you
make use of NDP, you would still have to manually configure DNS
servers)?
Use DHCPv6 or if your clients are supporting you can distibute DNS
information via RAs. Support for adding DNS info to RA is not implemented
on cisco routers yet.
The other hole, as was, is the lack of IPV6 help address
functionality on Cisco routers (well 6500s at least): if I were to go
down the route of using DHCP for IPV6, how could I use a central server
without this helper functionality?
No DHCPv6 helper functionality, but DHCPv6 relay functionality, however I
don't know the implementation status on various cisco boxes.
