Delete this record when it becomes stale

[Magnus Kirkerud]

Is there tool or script that can be used to list all host records in a DNS
zone where the "Delete this record when it becomes stale" setting is not set?

Regards

When you list a zone with DNSCmd.exe, I BELIEVE that all records which
can be aged will have [Aging:????] (where ????? represents the number of
seconds before the record becomes stale) -- check this.

If so, then the following (built-in*) commands will get you close:

dnscmd Your.DNS.Server /zoneprint yourzone.com. | findstr /v "[Aging" |
findstr /r /v "^;"

You can do better with add-on commands (Perl, grep etc) or if you know
all the details of FindStr which I almost never use except when offering
commands to those who may be dependent on the default tools.
