Subnet change, DHCP help
Posted on 2012-03-15
I am in the process of changing our subnet from a /20 to a /19 to make way for a large influx (2000+) of new PC’s coming in. All routers, firewalls, switches have been changed to the new subnet already. My last step is to change servers and DHCP. Currently we run a 192.168.0.0 network, 192.168.0.1 to 192.168.5.255 are static, and plenty of room for static's. DHCP pool starts at 192.168.6.0 to 192.168.15.254 and is nearing capacity.
As for DHCP, what would be the best approach to add more addresses to the DHCP pool with the new subnet. I’ve read a few things:
1. Doing a 80/20 split with another server and set a delay on the second one to prioritize
2.Delete the current scope and recreate with a wider address pool
3. Keep the current scope and create a super scope
I’m leaning towards just deleting the current scope and recreating with a 192.168.6.0 to 192.168.31.254 address pool. Thoughts? Do I need 2 DHCP servers?
