DNS records clean up

I'm doing some DNS server clean up, and in our .loc domain there are lots of old host A records for machines I know for sure have not been used in years (some time stamped as old as 2005).  Question is any reason to clean these up? I'm sure there is no harm in it, but sure looks messy.

Domain is server 2008.

It's always worth removing old dns records if they are not needed as they can cause conflict issues with newer/other records that may be using the same IP addresses/hostnames.

You should be able to scavenge the stale records by right-clicking the server in the left-hand pane on the dns window. This should automatically remove any old records from the system.

One reason is replication between DNS servers. If you install another DNS server you need transfer this DNS hosts obsolete. INMO this reason and save space disk.

Thank you both, Miguel I'm about to deploy a 2nd DNS, and that is precisely why I want it clean first.

Alright I've enabled it to scavenge with the default of 7 days. And told it to scavenge right away, how long does it usually take? I don't see any events in the event log letting me know it is running.

Found a good video, I didn't set it at the server property level.  However still no event, but I think if I understand this correctly it won't happen until 14 days from now since I set both to 7 days. Correct?
