[Pdns-users] IPv4/IPv6 nameserver preference by recursor?

[Darren Gamble]

Good day,

We just wanted to get some information on how the recursor behaves when
presented with a NS record set containing both IPv6 and IPv4 addresses,
and/or if a NS record name has both A and AAAA records.

If there a preference by the recursor to prefer one protocol over the
other?

How does the recursor handle a nameserver name with both A and AAAA
record types?  Is it capable of using both if one is unreachable?  Is
there a preference?

Thanks!
