I have a classC address broken down into 6 subnets (netmask 255.255.255.224).
I would like to take one of those subnets (Network x.x.x.192) and break
it down into several smaller subnets, of 7-10 addresses per subnet.
Is this supported by Linux? If so, any pointers or specific examples on how
to do this would be greatly appreciated. NOTE: This info isn't in the
subnet HOWTO.

Sincerely,

Brian Rankin

This would be either 8 or 16 addresses per subnet,
which is 6 or 14 host ip addresses.

Yes

I have got some ascii art in http://www.dsl.nl/~rob/test/nettree.htm
The (sub)network address + 1 is the 1st host ip nr in the (sub)network.
The next (sub)network address - 2 is the last ip nr in the (sub)network.
The next (sub)network address -1 is the broadcast address of the
(sub)network.

Subnetting a subnet is just like subnetting a net.

Rob

what are you doing with the other 2 subnets ?

Try looking at http://www.linuxhq.com/HOWTO/mini/IP_Subnetworking

This mini-howto explains everything that you ask.

There is a specific example in the howto as to what you are asking.
