Is this not true? Yes, it is true. There's no setting or configuration or software state that makes a server authoritative for a zone -- the authority comes from having been delegated by the parent zone. Any name server (whether it's QDNS, BIND, etc.) is 'authoritative' for a zone if the zone has been delegated to it by the zone's parent. For example, consider a zone domain.com, which has been registered with name servers ns1.domain.com and ns2.domain.com. The root name servers, which have authority for the root zone '.' and the com. zone, will have NS records: domain.com. NS ns1.domain.com. domain.com. NS ns2.domain.com. These NS records _delegate_ authority for the domain.com. zone from the root servers (which have authority for the parent zone, com.) to the name servers at ns1.domain.com. and ns2.domain.com. It doesn't matter what name server software is running on those machines for them to have authority. Being 'authoritative' essentially means that those servers hold the definitive data about the zone (a zone file). All other name server will get their information about the domain.com. zone from the authoritative servers. Of course, a name server that has authority for a particular zone must also have authoritative data (i.e. a zone file) for the zone. Otherwise, you have what's known as a 'lame delegation.' > If that is not so, then do I have to add my virtual domains to my ISP's dns > records? Only if your ISP's server(s) is listed with the registrar (NSI, etc.) as one of the name servers for the zone. If that's the case, then the ISP's server is also authoritative for the zone and needs to have authoritative data for it. Christopher Bort
