I think you meant "return a different IP address" rather than
"hostname". The way to do this in BIND is with a sortlist{} clause in
the options{} statement. This can get the name server to return a
sorted list of IP addresses for some host based on the order that is
"best" for the client making the request. There are also commercial
products like Distributed Director from Cisco which do something
similar.
