Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

When I create a new Domain Controller with dcpromo then the wizard will also add a DNS Role to the server because the first domain controller must be the global catalog server for the forest.

After the install when I look at the DNS then I see the forward lookup zone for the newly created domain.

However no zone is created for the Reverse lookup zone.

So my question is: Is this an advisable endresult or not? In other words is it a good idea to add my domain to the reverse lookup zone as well?

Just curious to hear how other people use this zone in the domain controller.

Thanks

A reverse lookup zone is not a requirement for AD and has no bearing on the operation of AD. As such, a rDNS zone isn't created as a part of the DCPROMO process. You can choose to create a rDNS zone for your subnet(s) or not, it really doesn't matter.

Ok clear! :) Then I'm not going to create that zone for the fun of it! Good to hear that its non-essential. Thanks for your answer and have a good one! –  Joost Verdaasdonk Jun 3 '12 at 21:47

fwiw I like having a reverse lookup zone just so that when someone gives me an IP address I can very quickly see which DNS name it maps to. –  Mark Henderson Jun 3 '12 at 22:05

I normally set up reverse lookup zones as well, but I wanted to answer the question as directly as possible. –  joeqwerty Jun 3 '12 at 22:12
    
Hi Mark and joe, Ok setting it up for such a purpose is at least a useful purpose. (although we have tracert too :) ) Ok now I have one I'm going to create it too! Thanks guys! –  Joost Verdaasdonk Jun 4 '12 at 16:27
