private/internal db file question...

[Gary Kline]

	Folks,

	After years or trying, I may have my private/internal
	DNS db files working.  From a colo machine I can reach
	my internal servers.  One small question for the DNS
	wizards out there::  are the last ".in-addr.arpa" lines
	considered good-form?  Can I blow them away or uncomment 
	them?  (I am considering building an internal mailserver
	[yes, with Postfix--it is better than sendmail].  iF and
	when I unload my DNS server, be nice to know.)

	thanks for any insights,

	gary
