DNS Records – Determine Ownership?

I have two A records for two computers, both with the same address.

One has a time stamp of 01.28.2013 (TTL – 0:0:15:0) while the other has a time stamp of 01.14.2013 (TTL 0:0:20:0).

With the setting in place to delete the record when it becomes stale and that period passing, I’m assuming I still have the record from 01.14.2013 present because it was not able to be scavenged due to DHCP not being the owner of the record.

Is there a way to tell the owner of the record in DNS?

You might look at the security tab and check out the owner information there. It's not always particularly revealing though.

If that fails there's no way to tell what made the record, although logically it's only likely to be the computer itself or any other servers you've made responsible for that task (such as DHCP).

Do bear in mind that DNS is responsible for scavenging, not DHCP. As such, it's permission to remove records is not dependent on DHCP. Your scavenging settings will mean it's stale? And the scavenging task has run?

Cheers,

Chris

The security tab will not show the actual owner of the record.

So it looks like there is no way to tell - which seems strange.
