What happens if I delete all of my DNS A and PTR records?
Posted on 2009-05-06
I have a slew of duplicate entries in my DNS on both of my domain controllers. Lots of A records for the same IP address in the forward lookup zone, and lots of PTR records for the same IP address in the reverse lookup zone. It looks like some of the entries have been there as long as the network has been in existence. I have it set up to scavenge records after 7 days, but that doesn't seem to be doing anything.
What happens if I just delete all of the A and PTR records from these zones? Will they regenerate gracefully? Or will I bring my network to a crashing, grinding halt?
