Nope. How would a given nameserver even know if some other, unrelated 
nameserver on the other side of the world had a record in one of its 
zones pointing to any given name or IP address? The decentralized 
administrative model of DNS does not lend itself very well to any kind 
of "backreferencing" capability. At one time there was such a thing as 
an "inverse query", but even that was only limited to the zones that a 
particular nameserver knew about. It was abused so badly as a poor 
substitute for proper reverse-DNS (address-to-name) resolution, that it 
was eventually deprecated, and isn't even supported by modern versions 
of BIND any more.
