I have a cluster of 2 linux servers that mirror DNS settings. These are my ns1 and ns2.

I now have a Windows plesk machine.

I am looking for information as to the cons of using ns1 and ns2 for the Windows server. So to use my services you would only have to know about ns1 and ns2.

Has anybody done this before ? Should I set up an ns3 and ns4 instead?
