Dear all,

This question may have been discussed earlier as i saw in the previous posts of the DHCP discussions. but I didn’t find the answer I need.

Here is my case .

I want to enlarge my network range , from using 255 IP addresses to using 1022 addresses. i am going to change my subnet range from 10.1.21.0-255 to " 10.1.21.0-10.1.23.255 " .

doing so ( changing the subnet mask ) is disabled when you go to Scopes>properties , the subnet mask is greyed and couldn’t be changed.
The question is that I have a lot of IPs reserved in a custom reservation list , i don’t want to import them one by one on manual basis, is there any way to import them when creating a new scope ?
what im going to do , is creating a new scope with the same address pool , address leases , reservations with enlarging the network range. this is the only way i Suppose to enlarge our network range , am i right ? and again my real pain in the ass is not to manually make a new reservation list. anyone can help

regards

perhaps this helps

for better advice you could start by telling what server type/version the dhcp server is running as there are several ways of widening the current scope

That didn’t help mate.
It say that you must delete a scope before adding a new one . but i need to migrate my Reservation list without manually add them one by one

what server are you running? is this an sbs?

usually you should be able to use netsh to do an export then import with parameters

hold on

googled it for ya
