DHCP Question

[scooter817]

Hi Everyone

I have a question, my manager is letting me do some work on the routers and switches since I have been doing UC for the last 8 years. He gave me a simple task to set up a DHCP pool. I've logged into the router and I see that they currently have one so I was going to just take the current setting that are there and work on them in notepad. What is wanted to know is the Scope the same thing as the network part of the DHCP Pool. And if so I wanted to know how do I find the subnet mask for the new network. The current pool has a network of 10.8.15.0 255.255.255.0, the new pool has a scope of 10.73.0.0 and the IP range is 10.73.1.100 to 10.73.1.190. Any help would be greatly appreicate and thanks in advance and have a great day.

There's a lot of documentation available on DHCP if you search, plenty of examples and videos:

Router(dhcp-config)# networknetwork-number [mask |/prefix-length]

As to the mask, that is something that they should have provided you. There are plenty of subnetting calculators online to help.

If you only need to hand out from 10.73.1.100 to 10.73.1.190, there is no mask that will make that happen, use a /24 and exclude the ranges you don't need.
