If you delegate DNS for subnets, the subnets can run Dynamic DNS if they like. If it's over RF, the encapsulating protocol (AX.25, D-STAR, etc.) can provide the callsign.
Keep in mind that any dynamic assignment scheme should keep a logfile or other record of who had which IP address when, so that problems can be tracked down, even if the assignment is no longer in effect. - Brian
