Supernetting questions

Supernetting questions

I would like to setup a supernet on our network. We currently have 1 subnet which is filling up quickly. I'm trying to get a feel for how much down time I need to schedule. My questions are:

"How will a supernet effect the current network settings on clients both DHCP and Static IP?"
1. Will the DHCP clients just draw the new subnet mask and connect?
2. Will the static IP clients still connect to the original network IP range using their current settings or will the settings all have to be changed to the new subnet mask?
3. Do I just expand my DHCP scope by setting up child scopes?

I am aware that I will have to change my router configuration and other settings.

It's a bit difficult to advise unless you give us specifics.
It sounds like you just need to take a bit off your subnet mask and then increase your DHCP scope.
Alternatively, setup a second subnet on a new VLAN with its own DHCP scope.

My current configuration is:

Giving us a range of: to

So in relation to my questions does this help? The immediate goal is to get more IP's available.

We plan on setting up VLAN's for specific uses in the future.


RE: Supernetting questions

Yes, that sounds fine - change the IP settings in the DHCP scope and you're fine.
You'll need to reset each device on the network so it picks up the new subnet mask (and default GW, if you change that).
Also, you will need to reconfigure any device with a static address, eg switches, printers, etc...
