Subject: RE: Gothcas of changing the IP Address of an Authoritative DNS Server
Date: Wed, 14 Dec 2005 13:15:42 -0600assuming you've got the old box and the new one running
concurrently, you could run tcpdump on the old box with a
filter to only catch dns requests to the old ip. Let it run
for 24-48 hours and you could see who/what was still
querying the old ip.
This topic comes up frequently on bind-users@isc.org ...
Might query there but many of these responses have covered much of what is
discussed there.
