The RFC you are looking for is RFC1597 - Address allocation for private
>From the document:
The private class C addresses are 192.168.0.0 through 192.168.255.255
The private class B addresses are 172.16.0.0 through 172.31.255.255
The private class A addresses are 10.0.0.0 through 10.255.255.255

Are there any private class C addresses?
I know that 10.0.0.0 is a "private" class A address (private meaning that
packets routed to this network will not be forwarded over the internet, i.e.
intended for internal use...)
I know that 22.214.171.124 - 126.96.36.199 are private class B addresses
(there is another range too).
I want to know if there are any private class C addresses. (i.e. of the form
x.y.z.0). I'm getting the impression (from following previous threads on this
discussion group) that without a gateway, my class C address is not going
to play nice with class
B addresses on the same network (constantly logging addresses as new
due to net masks...). If a private class C address exists, I could just use
that (actually I may need a couple of class Cs).
If you could point me to an RFC for this, that would be great.
