2nd subnet??

The_KiD · 22 Mar 2007 at 08:59

Right before we go any further, please remember to speak slowly and clearly. I can find my way round a network and and I can do a lot of things on them, however my knowledge only comes from me messing around with things, so I am no expert.

Ok here's the problem.

We are running out of Internal IP's on our work network. I think we have about 19 left EEEeeeek!

So how do I go about getting more internal IP's? and making sure they can all talk to each other ?

I think what I am looking for is called a 2nd subnet and our current internal IP is 10.0.10.X so I would set up a second subnet of 10.0.9.X for example, but how?

We use AD and DHCP and any help is greatly appreciated.

must say I like matja's idea more, would this be ok ?

matja said:
on machines with static IP's : change your subnet mask to 255.255.254.0
on the DHCP server(s) : change the lease subnet mask to 255.255.254.0 and modify the lease settings to include 10.0.11.*

effect : addresses 10.0.10.1 to 10.0.11.254 will be available (510 IPs) with no router craziness.

I just went to check out if this would be possible, but the subnet mask in the DHCP is greyed out.

How can I change it?

Good plan, however as my last post says, I don't seem able to change the subnet

*BUMP*

Anyone know if what JonnyBoy says is correct? Looks like it is, but would hate to go through all this hassle to find out it wasnt.

Oh and thanks all
