You need a 'real' network address. If, as I suspect, you're doing all  
of this on a single machine which isn't connected to a real network,  
then you can just use one of the addresses in the 192.168.x.x private  
network range.

If you're purely setting up Kerberos for the purposes of bringing up  
an AFS cell on a single machine, then you'll probably get away with  
the Kerberos realm being LOCALDOMAIN (you'll want to call your AFS  
cell 'localdomain' too), but it's not generally recommended. Kerberos  
can get upset if there isn't a working DNS system behind it.

Cheers,

Simon.
