You need a master with a fixed address.
Well its more that we havn't written the code to do it. We actually have the protocols to support nameservers being dynamically addressed (other than the root servers). UPDATE is capable of updating both glue and actual records. We lookup nameserver addresses for things like NOTIFY. There is nothing to stop a nameserver looking up addresses for AXFR. We already authenticate all these operations using TSIG. It's been on my personal TODO lists for over a decade now. > If your zone content and IP address don't change often you could set a > very long expire time on the zone, and fix the master definition on your > provider's slave whenever it breaks, but that's pretty fragile. > > Good luck, > > Doug > > _______________________________________________ > Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe > from this list > > bind-users mailing list > bind-users@lists.isc.org > https://lists.isc.org/mailman/listinfo/bind-users -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: ma...@isc.org _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
