Questin about zone file size

what ( if there is any ) is the max number of zones can i have with
bind 9.2.2?
I am creating reverse entry's for an internal network ( friggin huge ).

i was starting to think, this is alot of entry's.

basically i have 22 networks under one zone master. each network is a
/16. i am only providing records for the first 20 blocks, but still.
(254 x 20 )22 forward and reverse = "gulp". i don't want to overload
this system or cause such a *** delay that the clients willl break
out the pitch forks.

any words of wisdom or am I just being paranoid as usual, and bind will
handle this just fine :)

In article <brog3r$11qa$ XXXX@XXXXX.COM >,

I've seen reverse zones for /16 networks with records for all 64K IP's
(most of them obviously boilerplate, e.g.

I recommend keeping the zones smaller, so that when you make a change
the server only has to reload and re-transfer a small zone file
(although if you use IXFR, the transfers may not be an issue). I like
to have a separate reverse zone for each /24 in a /16.

I appreciate the reply.

how hard would it be to split up my 1 large zone into multiple smaller
how would I go about making things smaller?
right now i have one master zone file "" with a million
friggin entry's.
would it change anything to my clients if i were to break that zones up
like;,, etc...

for the longest time i have had one big zone file, but it had only 1/3
full resolution.
