Subnets and DHCP Scope

[Retrospec]

Hi all,

 

I have been asked to do some changes on our company network. However i am quite unskilled in the dhcp/subnet area.

 

We currently have a subnetted class C network that has been split into 4 subnets /26

Our main office utilize the adresses 192.168.100.129 - 192.168.100.190 /26 Before my time they had a branch office at another location using

another part of the subnet 192.168.200.129 - 192.168.200.190/26 However this subnet and the other 2 does not exists anymore and the main office is running

out of available IP adresses. My question is, can i add this as an additional scope on the dhcp server and utilize the adresses at the main office?

And how if it is possible am i doing it? Is it as simple as just adding a new ordernary scope and copy the scope options from the old one?

 

They dont want to re-design their subnet to change the setting of servers/routers et.. And i only have basic knowledge about this.

If you don't have reservations on your DHCP main office I say just delete the scope (after work hours) and create a new one with /24 (or bigger if you need). If you have some reservations you can create those by hand in a couple of minutes; if there are more then a few, use netsh to export and import them. If none of the above works for you, create a superscope in DHCP then add a scope on this superscope with the rest of the IP addresses.

 

Using superscopes: Dynamic Host Configuration Protocol (DHCP)
