Subnets and communication between?

[wjohnson24]

I have an existing network of 10.1.0.xx, the existing router is set up as 10.1.0.1, my domain controllor, DNS server, and my exchange server are also on the 10.1.0.xx network. The subnet mask is 255.255.255.0. I know that will not work for subnetting.

I need to know a subnet mask that will allow for a few more networks, and what I have to do to get them communicating back and forth between each other, because we will still only have the one dns and exchange server on the original 10.1.0.xx network and the subnets will have to be able to get to those servers for email and internet.

I am also wondering if it wouldn't be easier to just bring up a new domain controllor on the existing network and have the new computers log into that domain controllor?????

What are you trying to do and why do you think that you need additional subnets? Do you have more than 253 computers on this network? Is your DNS/Exchange server overworked?

It is trivial to assign another subnet to your network. For instance you could just start putting 10.1.1.xxx devices on the network, configure your current default gateway (probably your router) to have a secondary address of 10.1.1.1 on the existing interface. That will automatically create a route between the two subnets. You will need to reconfigure your DHCP server to service both subnets (assuming that you are using one). That will allow you to install more than 253 machines on your network, and everyone will be able to access everything on the network.

But if your domain controller is overworked, then this really won't help at all.
