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. _______________________________________________ questions mailing list [email protected] https://lists.ntp.isc.org/mailman/listinfo/questions
