[Pdns-users] How to set up pdns recursor to repeat the query if it does not get an answer

[Winfried Angele]

Hi Mira,

Yes the Recursor does no retry on *this* auth. But it tries on the other nameservers from the NS RR set. IPv4 and IPv6. So if you have only one auth, Recursor tries two times, IPv4 and IPv6 if available.
