I'm using the Linode DNS manager for my domains. I just added IPv6 support to my server using Hurricane Electric and can ping IPv6 addresses.

I want to set up an AAAA DNS record for my server in the DNS manager, but can't get it to take. It's probably some newbie mistake. Here's my HE config:

Code: Global Tunnel ID: 47007     Local Tunnel ID: 460
   Description:    
   Registration Date:    Fri, Jan 22, 2010
Tunnel Endpoints
   Server IPv4 address:    209.51.161.58
   Server IPv6 address:    2001:470:4:1cc::1/64
   Client IPv4 address:    72.14.188.42
   Client IPv6 address:    2001:470:4:1cc::2/64
Available DNS Resolvers
   Anycasted IPv6 Caching Nameserver:   2001:470:20::2
   Anycasted IPv4 Caching Nameserver:   74.82.42.42
Routed IPv6 Prefixes and rDNS Delegations
   Routed /48:    Allocate /48
   Routed /64:    2001:470:5:1cc::/64
   RDNS Delegation NS1:    none
   RDNS Delegation NS2:    none
   RDNS Delegation NS3:    none

I've tried both the client IPv6 address and the server IPv6 address, and the DNS manager tells me they are not a valid IPv4 or IPv6 address, so what should I be using?

Are you entering the netmask (/64)? As with IPv4 addresses, that's only needed for interface configuration; don't include it in DNS records.

Also, the Server and Client IP addresses are for the actual point-to-point link between you and HE... if you want to set up reverse DNS or use multiple IPv6 addresses, make sure to add an IP from the Routed /64 to eth0 and use that.

hoopycat has your answer.

Additionally, I'd like to inject my spiel about not using your point-to-point address as a routed IP address on your Linode, given that HE does not permit you to alter your rDNS (they're discouraging you from using this address).

I recommend assigning something out of your routed /64 to your Linode as its communication address and keep the point-to-point address limited to your tunnel configuration.

You know what would be really neat, Jed... Native IPv6 on Linode. :-)

Idiots guide for that?

From my /etc/network/interfaces:

Code: iface eth0 inet6 static
   address 2001:470:1f07:f41::dead:beef
   netmask 64


, with 2001:470:1f07:f41::/64 being within my Routed /64. -rt
