[lug] single zone file for rfc1918 addresses

[charles at lunarmedia.net]

all-
i have, what i hope to be an easy dns question.
i would like to incorporate all of my rfc1918 addresses into a single db
file for reverse dns lookups.

the model i have in place, is similar to:

$TTL 86400
@	IN	SOA	nameserver.foo.	admin.nameserver.foo. (
			2001031700	;Serial
			10800		;Refresh after 3 hours
			3600  		;Retry after 1 hour
			604800		;Expire after 1 week
			86400 )		;Minimum TTL of 1 day

	IN	NS 	nameserver.foo

$ORIGIN 1.1.10.in-addr.arpa.
;10.1.1/24
1	IN	PTR	blah.foo
2	IN 	PTR	blah2.foo

$ORIGIN 3.3.10.in-addr.arpa.
;10.3.3/24
1	IN	PTR	blah3.foo
2	IN	PTR	blah4.foo

$ORIGIN 254.16.172.in-addr.arpa.
1	IN	PTR	blah5.foo
2	IN	PTR	blah6.foo


I *think* this is a valid db file. However, I am not so certain as to how
to call it from within named.conf.
I already have a

zone "." IN {

entry for my root server information.

how can i call this file to create a central point of administration for
my rfc1918 addresses?

thanks! -charles
