<br>
It very much depends on the reasons for the forward entries. <br>
<br>
For example:<br>
<br>
Commercial backup software for Microsoft servers require <br>
forward-reverse-forward matching. They won't move bytes <br>
unless a lookup returns an IP, the reverse lookupo returns a <br>
name and a forward lookup for that name matches.<br>
<br>
Commercial and open source email handlers are often<br>
configured (some as a default) to refuse or quarantine messages<br>
from inbound sessions using non-matching host==>IP==>host <br>
entries.<br>
<br>
If it's for a local experimental lab, it might be a waste of your <br>
time to even create the reverse zones.<br>
