How do I add an IP range to Windows network?

We have 3 windows 2003 servers and many client PCs.

Our IP range is currently on a mask.

We are running out of IP addresses and I need to add another 254.

What is the best way to do this without compromising the AD stabilty?

I was thinking of just adding a new IP range on the server NIC e.g. 192.168.2.x

Would this cause problems?

    Change your network address from a class C to a class B.


    This will give you a whole lot more hosts in your IP range because 192.168.1.x thru 192.168.254.x are effectively in the same range.

    You will need to do this on your DHCP server ad test to make sure that it works OK,

    Or simply add another range.

    I hope this helps !

    I would recommend to add a different network with a router to do routing between. Not something you'd like I know.

    But the thing is by reducing bits from subnet mask on range, you're essentially doing 'supernetting' which may not be understood by some legacy devices (like old printers etc).

    i agree. I would add another class C range in DHCP, It's harmless
