This type of setup won't work.  You have to differentiate between what is 
possible with Kerberos/GSSAPI and how are existing applications (e.g. 
telnet,ftp,HTTP) using it. With telnet,ftp,HTTP you are bound to DNS 
resolutions (A record and reverse, hosts files are possible but painful). If 
you write your own Kerberos/GSSAPI applications you can define it yourself 
and can do it independant of DNS.
