the original question was:

nslookup will map the IP number to host name. the way to do this
was in the BIND FAQ that is located at:
www.isc.org/bind.html
this showed that my configuration, at least within the subdomain is
correct. i've included the relevant part from the FAQ. according
to several people, rlogin does not support IP address. so nothing
was wrong there and i guess that i can believe the man page.
now the next step to to find out why my parent domain is having
problems resolving clients in my subdomain.
