Our network ran out of IP address on the current local subnet, so my boss requested our service provider to change our subnet from /24 to /20, it will give us more than enough IPs to assign to the devices. Currently there is a DHCP server setup on a Win2k3 server, it is serving IPs to the local network.
Our current IP is 10.10.10.1 to 10.10.10.254, once on /20, it will below 10.10.10.1 to 10.10.15.254.
My question is what or how to implement the /20 on the DHCP server, so that it will serve more than 254 addresses. For example, if I want from 10.10.10.1 to 10.10.5.254, this will give me enough device IPs, but I'm not sure how to set this up in DHCP.
If I remove the current IP scope and re create a new scope start from 10.10.10.1 and end with 10.10.5.254, will it accept on DHCP? will my devices obtain IPs from this new scope between this range?
