No forward lookup for one domain

[Gerald Waugh]

I have a domain name frontstreetnetworks.net 216.175.178.41
in a subclass 'c' network 216.175.178.32/28 
Nameservers:
fsn1.frontstreetnetworks.net.     86400   A       216.175.178.41
fsn2.frontstreetnetworks.com.   86400   A       216.175.178.46
fsn3.frontstreetnetworks.com.   86400   A       216.175.178.45
My reverse lookup does not seem to work, 
following is output from 'dig' 216.175.178.41 
any ideas?

[admin at www admin]$ dig 216.175.178.41
