If we use a name like ipv6.pool.ntp.org, we have lost. [...] I believe each IPv6 address will add 26 bytes to the response, 2 for name pointer (compression and all), 4 TTL, 2 class, 2 type, and 16 for the IPv6 address itself. This means we could add 4 addresses easily,and if a few less A records were presented, more. Each A record removedwould give us back approximately 16 bytes.
I agree with you that we shouldn't need to use ipv6.pool.ntp.org.Wouldn't it be possible to return ipv6 addresses when queried for AAAA RR and ipv4 addresses for A RR? I haven't experimented with DNS on ipv6, but it seems to me that an ipv6 host should query for AAAA RR.
