Re: [Pdns-users] Request for Help with PowerDNS + Recursor Configuration for Final Year Project

Hi Nacho, How "static" is the list of domains which need to resolve locally? Updated sub-second? Once every minute? Once every hour? I would not use pdns-recursor at all. I would let dnsdist be the first point of entry, with 2 pools: a "auth" pool and a resolver pool. Add the pdns-auth (with M
