Loopback Address - DNS

Hi Guys,
I have a single forest and 2 domain controllers.. im seeing different opinions on how to set the primary and secondary DNS in the NIC.. they way I done it is: Primary DNS set IP to itself and secondary to the other server - for both DC's- is this best practice?

Another option is this:
-on each DC, always put the other DNS as its primary DNS server
-each DC should include the loopback address 127.0.0.1 in the list of DNS servers, but not as first entry.

I always configure them as per your first suggestion.  Each DC points to itself and then uses the alternate DC as the secondary DNS.

Been doing it for 10 years and has never caused me any issues.

It is one of those questions that comes up here and sparks a debate.  

My logic is that the DC's should be able to resolve from their own DNS when required.  They should also be able to stand alone to do this in the event of one of the DC's failing.

No need for any static entries, if they are DC's they should create all of the necessary records in DNS automatically.  The DNS should then replicate between both DC's providing all is well
