Ok, thanks a lot for the reply. Lets pretend that the names in the RFC are still the ones used. If the client queries the "a.isi.edu." name server asking for the A address of the "c.isi.edu." server, the zone information from "isi.edu." must have this address in the name's list, right? Many Thanks Best Regards, Luis
