This is part of the reason I favor having dynamically updated Forwarding Information Bases for D-STAR frame addresses and not even assign an IP to the frame address. On a highly mobile station, that during a QSO might switch between gateways you don't want to wait on centralized updates or DNS cache refreshes.

Don’t believe that DNS updates are instantaneous. In common configuration, IP address changes can easily take 6 hours.



And if you pull the TTLs down to something short, you start to bang the heck out of the centralized name servers. Whoops, let me say the one centralized name server, because zone replication timeframes will also add a lot of delay.
