Well, technically your correct, but in practical usuage it depends on your
registar.
I own a few domains that have a single IP for both Primary & Secondary.
They point to my cable modem at home. Kind of stinks, but I have a DHCP
address attached to that bad boy. Luckily it hasn't changed since I got
it (knock on wood).
but I set mine up like
ns1.domain.tld => 1.1.1.1
ns2.domain.tld => 1.1.1.1
I use GoDaddy.com as my registar, and they dont seem to care one bit!
So, in short, it is possible to have a Primary & Secondary DNS server that
share the same IP address.
It isn't recommend though. Nor is it recommended to have them on the same
network either.
Recommendations though are made to be broken!
