[Pdns-users] Questions on powerdnssec

Hi All,

 Few questions on using PowerDNSsec - using the latest RPM build (20110509.2190-1) in our IPv6 labs. Fundamentally - PDNS auth, Bind Recursor and Win7 client behind router, all dual stacked.

 Firstly,  when using an external server as a recursor; can this be an IPv6 host ?   I have the auth server forwarding  to bind for any recursive queries, this works when I specify the bind IPv4 address, but not the IPv6 address. Both queries work fine if querying bind from the pdns server directly using dig on ipv4 or ipv6.

 Secondly, when using powerdns secure-zone and the gmysql backend, I`m guessing rectify-zone must be ran whenever any records are created to resign the zone.  This being the case, does this lead to having a hidden master (ie: non publicly accessable) host or db in order to be slightly more secure [making the running of the signing process hidden] ?

 Finally, Is there any documentation of the validity length of the keys, or do these rollover automatically ?

 Bert as you thought, this build this resolves the issue I had with mysql going away and the server taking a while to reconnect. Its serving records from the cache just fine.
