DNS on Windows Server 2003, 3rd Edition

Looking Up CNAMEs

At times you may want to look up a CNAME record itself, not data for the canonical name. With nslookup, this is easy to do. You can set the query type either to cname or to any and then look up the name:

C:\> nslookup 
Default Server:  wormhole.movie.edu 
Address:  192.249.249.1 

> set query=cname 
> bigt 
Server:  wormhole.movie.edu 
Address:  192.249.249.1 

bigt.movie.edu  canonical name = terminator.movie.edu 
> set query=any 
> bigt 
Server:  wormhole.movie.edu 
Address:  192.249.249.1 

bigt.movie.edu  canonical name = terminator.movie.edu
