Hello Vinicius, You can do that with Lua records. createReverse(), createForward(), createReverse6() and createForward6() can be used to create generic records. Here is a good starting point: https://doc.powerdns.com/authoritative/lua-records/functions.html#reverse-dns-functions Winfried On

Does this only happen with DoH frontends? Did you try with UDP frontends as well? Sounds like a bottleneck on your backends imo. Winfried Am 23. Juli 2021 13:32:39 MESZ schrieb Yannis via Pdns-users : >hello, > >We're using dnsdist (1.5.1 on Ubuntu 20.04, 16 cores, 32GB RAM) as a >DoH

Re: [Pdns-users] udp-in-errors , AXFR and zones timeouts

Hello Marcello, Verry good! But in my opinion the DNS server should not send out SOA queries faster than it can pickup the answers. Raising the buffers helps only up to a certain burst length. If you have more zones, the problem comes back. Winfried Am 29. Dezember 2020 09:17:06 MEZ schrieb

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

Hi Mira, I think if a Resolver retries on possibly overloaded or attacked authoritative DNS servers, it gets even worse for them. So I'd recommend to try to contact the people in charge for that domain and try to convince them to solve the problem on their side. And again, the Recursor tries

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

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. Winfried Am 18. September 2020 14:47:49 MESZ schrieb Mira Krejci via
