I would expect ISP's would accept updates on their own servers but may support a delegation being added. > Hm, need to filter at the edge, make sure customer's don't update > each other's records.

You can send to any nameserver listed for the zone with a preference for the one that matched the SOA MNAME. You can find the zone by doing a query for SOA <name of record to be added> I have a expired draft which says to make the response to this have a 0 ttl if it would be a NXDOMAIN so you use any cache and not have the search poison the cache with a long lived NXDOMAIN response. The SOA's owner in the authority section will match the zone's name. From that you can get the zoness NS records etc. It authoritative servers don't do RFC2308 you just stip the left and label and try again. You will get a SOA when you reach the zone apex. > Lee > -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: ma...@isc.org _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
