Just ran into an issue with recursive DNS servers where the two servers have
cached a different A record for mirror.centos.org.
This is a problem as the firewalls permit access to the FQDN, which presumes
that both the client and the firewall end up with the same A record for the
domain.
I'm intending to swap these recursors out with PowerDNS servers, but am
wondering if there's a way to keep the record cache in sync between multiple
recursors.
