DNS entries for servers with a time stamp
Posted on 2011-03-07
I think we may have a few issues with our DNS and I am trying to resolve these. The issues seem to be:-
1. I have a number of servers that even though they have a static IP address in DNS they seem to have a timestamp date while others have static. Is this correct or should they show static in the timestamp if they have a static ip address?
2. I have a number of desktops who share an IP address some of which have a time stamp date and the out of date machines have a static time stamp. I assume it is safe to delete these old static records?
3. I found a number of instances where I have two machines sharing an IP address (as I have already mentioned) the problem also seems that one of the machines appears in the forward lookup zone but not the reverse and the other appears in the reverse but not the forward.
I know these problems are not good but how do I go about fixing the issues?
