It has been a few years since I last operated a DNS server but ISTR that
DNS records have a Time To Live (TTL) associated with them and systems
don't get "renumbered" often! At least systems with static addresses
don't get renumbered often. If a server is using broadband cable or
ADSL, it may not have a static IP address but, once again, its address
is not likely to change while it's up and running.
If there is a problem reaching a server, one might try re-resolving its
address but that is by no means the first thing I'd try.
