Hi gurus, i need your help.
I wish to segment my network which uses Class C IP addresses. Currently almost all the ip addresses are used up (254). I wish to create a domain made up of three (3) sites and about 600 pc's. I have the following concerns and i need you guys out there to help me out.
1. Can i have still use my class C addressing to create 3 sites, ie each site having 200 hosts and all in one LAN? What i am thinking of is having something like the following,,

Would this mean i have subnetted my network? Would i be better off using a Class B addressing? I feel there would be a huge waste of Ip addresses. Can someone help me out?

You can but if you need to add more hosts to those subnets you'll run out of addresses pretty quick. I'd go for the Class B to be sure. Keep in mind that you'll need router(s) to connect the different subnets.

Don't worry about it being a waste, you are using private IP addresses, they are free :)

I would use 3 10.x.x.x subnets:

This will give you 65,534 IP addresses per subnet so you won't ever have to worry about "re-subnetting" again.

You don't need to create 3 sites if all computers are in the same location and connect to the same network. Go to a class B network with local addresses. You can use -, these are local B class addreses assigned as in RFC 1918.

I forgot to say that if you use 3 different networks you'll need routers between them, so better go to class B.
