Host Records with Same IP Addresses

[David]

We have about 75 computers in our domain, about one third of which connect
remotely thru VPN. Many records contain the same IP address as one or two
other host records (remote hosts always appear in the repeated IP address
record groups). Is this a problem? A couple of host records are repeated,
containing exactly the same host name and IP address. Is that a problem, or
should I delete the extra record? Or will DNS automatically clean up the
records?
Thanks for the help,
David

Dynamically created records will have a timestamp on them. If the machine is
know to be a dynamic host, delete the records without a timestamp or if it
has an old timestamp.
DNS will not remove records without a timestamp, DNS considers them static
records.

Name, Type and Data are the only columns available in the DNS MMC, no
timestamp. How do I find the record timestamp?
Thanks again!

If you flip the DNS MMC into Advanced mode, the record properties page will
show you the timestamp.

Thank you so much! And I thought I was already somewhat advanced!
