I'm setting up two DNS servers for the company, so far so good, the system is based on pfSense and bind as the DNS server.
The interesting part is, checking the record from our current DNS provider, I noticed A Records for the nameservers, example:
; ; Zone NS records ; mydomain.example @ 0 NS ns1.dnsserver.example. ns1.dnsserver.example. A 192.0.2.6 ns1.dnsserver.example. A 192.0.2.7 @ 0 NS ns2.dnsserver.example. ns2.dnsserver.example. A 192.0.2.8 ns2.dnsserver.example. A 192.0.2.9
Now, I don't understand this, the GUI from pfSense, doesn't allow me to set this records for
dnsserver.example is a different zone.
