[Pdns-users] ODP: PDNS Recursor - force IPv6

[Marcin Gondek]

Hi All,

Correct, prioritize IPv6, fallback on timeout.
As far is now not possible now, do we have chance to add it in newer version?

Why this could be needed:
If case of CGNAT/NAT and so on, some people may have resolver on their homes.
They may have public IPv6 address but IPv4 shared which could be limited on nameservers side.

Thanks,

I think since 4.5 we do the right thing and *only* use v6 if you set query-local-address=::
But that has the consequence that a lot of (v4 only) nameservers become unreachable.

Ah yes: sorry I misunderstood the OPs requirement "force usage of IPv6".  They wanted something less strong: prioritise IPv6 (if both available).
