nameserver name

[Luis Silva]

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
