Re the latter point, I can see the advantage of being able to move a primary server to a new IP address without needing slave/s to update their config. On the other hand I can see possible chicken/egg issues in some instances, for example testing axfrs before a new domain comes online, or a domain disappearing even temporarily ([re-]registration problems, politics or other upstream failures) where specifying masters by IP address keeps things rolling. At least consider keeping config-time hostname resolution of masters optional? And I guess the same principles apply to allow-transfer, forwarders and other address lists? cheers, Ian _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
