	The name of the zone file is irrelevant.  You could call it 
SlartyBartFast and it wouldn't make a single bit of difference.  No 
one outside of your machine will ever see that filename.

	What is important is the fact that you tell BIND what the file 
contains, so that it can properly fill in the blanks.  The label used 
in the "zone" definition in the /etc/named.conf file is how BIND 
determines what the origin (e.g., "@") will be defined to be.


	That said, to make your life in the future easier, and to make it 
easier for someone else to come in and help you with domain 
administration, it does make sense to apply certain rules to the 
filenames you use.  Towards that end, using a name such as 
72.43.45.195.in-addr.arpa would probably make more sense.  You could 
also specify the ending fourth octet, and call it 
72-80.43.45.195.in-addr.arpa.
