So I was playing with nslookup on some bogus addresses, for a script.
and I ended up getting some unexpected behavior.

Code:
IP="192.168.1.1"
nslookup $IP
Lookup failedServer: A_vaild_address*
Address: A_vaild_address


** server can't find 1.1.168.192.in-addr.arpa.: NXDOMAIN

The IP used in the NXDOMAIN field is backwards. Is this the normal convention for looking up domain names from IP's?

*same results on different DNS servers
