DNS scavenging

I inherited a domain that's 15 years old.  The DNS has NEVER been scavenged.  I found IP addresses from a site that hasn't existed in 11 years.  I found DNS for computers and servers that haven't existed for 10 years.  Basically, DNS is a mess!

I want to turn on scavenging.  The powers that be want to be sure nothing will break.

So, what could break?

As I understand it, scavenging will only delete dynamically assigned IP addresses older than the specified date.  Is that correct?

What unintended side effects could there be if I turn on scavenging for a DNS that's 15 years old and never had it turned on?

Thanks

Cliff

What could break?  Access to any server that relies on a DNS lookup of local records.

Basically, any records that aren't static and that aren't being updated are subject to scavenging.  So to ensure there's no breakage, you first have to ensure that all required records are either static or being dynamically updated.  This post lays out just about everything you need to know.

So, if all your records are being dynamically updated (or static and thus not subject to scavenging), nothing will break.
