how to setup class b ?

[Daniel Wittenberg]

I want to setup a class B of dhcp address, with the first class c being
reserved for special things, like routers, servers, etc.  I have the DHCP,
and forward lookups are fine.  The problem in the in-addr lookups don't work
for anything in the first class c.  My guess is the way I setup the file:

<normal stuff here>
 0.1    IN    PTR    router.company.com
0.2    IN    PTR    server.company.com
1.1    IN    PTR    dhcp-1.1.company.com

If I can't use 0.x for the first 255 addresses, how would you set this up?

Thanks,
Dan
