Cleanup of Static DNS A records

    Question

  • Hello,

    My company has thousands of static DNS A records and there are many records which should no longer exist. I have a script to pull all static DNS A records for a specified zone and I have another script to ping and timestamp the responses - I'm trying to build up a history to say there was no response over the last 6 months so they should be safe to delete. 

    Has anyone else had to cleanup static DNS A records and how did you do it? There has to be something better out there.

    Please don't mention scavenging as i'm not looking to cleanup dynamic records and setting all static records to expire is not a valid option.

  • Hi!

    We've had to do quite some DNS cleaning yeah, we always did it manually to avoid disasters.

    Of course you will have the human error factor there, but what is important is to document everything you delete :-)

    There are probably better approaches, but I believe it also depends a lot on the environment in question and the severity/importance.

    Kind regards,
    Leon
