I have 4 servers set up with one as the master and the other 3 as slaves.  All are running Bind 8.2.1...In ALL cases I can do an nslookup for an address such as 161.205.x.x and I get the correct hostname BUT I can't do this for my 10 network on ANY of the servers, master included.  I can do the nslookup from hostname to ip address.  Any ideas of where I can look for help?
