Additionally for DNS don't forget to add IPv6 glue for the nameservers for your zones to the parent zones.
For named in particular listen-on-v6 needs to be specified as it is not on by default e.g. "listen-on-v6 { any; };". Named will ask questions over IPv6 by default even if it isn't listening on IPv6. -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: ma...@isc.org
