What DNS server to use ?
[si] Shadow Hawkins on Thursday, 20 March 2008 11:03:41
Hi! After setting up up IPv6 connectivity, what DNS server should I use ? (for resolving IPv6 addresses) My current ISPs IPv4 dns server haapens to resolve IPv6 (AAAA) addresses, but what about other cases ? What server should be used ? Regards, David

I also can't find any information on a DNS server accessible from IPv6 land. I'm using gblon02, and I've searched their site and guessed a few names and I can only find their IPv4 addressed name servers. Could their be some more info listed against the PoP's page on SixXS including core services like DNS and NTP?

SixXS doesn't provide any public caching recursive DNS servers (at least at the moment, there where ideas about this but never anything really concrete). As such, for the moment, you have an IPv4 ISP who provides you with IPv4 connectivity, as such you can use their resolvers for doing both IPv4 and IPv6 lookups. Another method of course is to install your own local _closed_ caching recursive resolver, on a node that has IPv6 connectivity. Note the closed bit, open caching recursive DNS servers are prone to become ddos sources, we rather do not see those. Thus apply your ACLs properly.

OpenDNS' nameservers have IPv4 addresses only, but are surely able to resolve IPv6 addresses: - 208.67.220.220 - 208.67.222.222 http://opendns.com/ Cheers, Klaus

You should potentially be able to use any DNS server, though your mileage might vary. I have just checked that my provider (Sympatico) supports the AAAA addresses, by using dig: dig @142.217.192.9 ipv6.google.com or dig @142.217.192.9 AAAA ipv6.google.com In most cases I would check your primary ISP's DNS and then slowly look wider until you find something. Of course if you are wanting a pure IPv6 solution then you would need to find a DNS server that has an IPv6 address itself. As for DNS servers that have IPv6 addresses themselves, the root name servers do: http://en.wikipedia.org/wiki/Root_nameserver and the IETF have a couple listed here: http://wiki.tools.isoc.org/IETF71_IPv4_Outage though I am not sure what their usage policy is. There are bound to be others.

I wouldn't encourage anyone to use the roots for client setup any more than I'd recommend end users to point to stratum 1 NTP servers. So, please, kids, don't try this at home. :)

I wouldn't recommend anyone to use the root servers, and I should have probably added the disclaimer. They get hit hard enough as it is. Your first port of call should be your ISP, since they are generally going to provide the best response time.
