Presumably (amongst other things) there has to be logic that avoids promoting glue to authoritative data. e.g. client A creates a host object www.undelegated.example and the registry doesn't know at that point whether or not A is about to create the expected domain object. e.g. the domain deadbeat.example has a number of subordinate host objects used by other domains; what happens to those host objects when deadbeat.example is cancelled? > I don't think that condition is part of the EPP data model; the criteria that > matters here is that the host object's name is subordinate to the name of the > zone produced from the registry, which means that one or more address records > for the host are required. That makes sense. Tony. -- f.anthony.n.finch <[email protected]> http://dotat.at/ Trafalgar: In southeast, northerly 4 or 5, occasionally 6 later, but becoming cyclonic 5 to 7 later in far southeast. In northwest, variable 4. In southeast, slight or moderate. in northwest, moderate. In southeast, fair. In northwest, mainly fair. In southeast, good. In northwest, mainly good. _______________________________________________ dns-operations mailing list [email protected] https://lists.dns-oarc.net/mailman/listinfo/dns-operations dns-jobs mailing list https://lists.dns-oarc.net/mailman/listinfo/dns-jobs
