I have a class C network. I have ran out of IP addresses, How do I do subnetting.

use private IP subnetting with class 10.0.0.x to 10.0.0.254 range and subnet 255.0.0.0 or get a shareware subnetting utility and calculate your own subnets, (remember the word "private" IP addresses).

I forgot something, remember to use one of those class "c" IP addresses as your "gateway" for that new sub-net.

If you have used your entire 256 addresses, you will need to register for more addresses and use a router. If you are lucky enough to get a contiguous clas C address, then you can supernet. subnetting will not solve the problem as described. Feelfree to write me with specifics and I will see if I can assist. You can also IM me at RCASCCNA.
