Reverse lookup zones are not essential to the operation of AD, Exchange or
SQL but it is one of those things that should be configured as best practice.
Also you will get events in the event log if you do not configure AD sites
and services site IP. You can just ignore them but it is a good to have
things just so.
That’s right Exchange and SQL are generally connected to by host name.
The servers them selves will re-bind to the new IP and all the clients
should connect by host name which has not changed. You may wish to check the
way your Apps connect to exchange and SQL just to make sure. I have seen
sites where people have installed software and hard coded an IP address into
their SQL connections.
The other things to look for are applications that use POP3 and SMTP for
some reason people that set up apps tend to use the servers IP address. I
don’t know why perhaps it’s just lack of experience or just laziness.
