I have a device which acts as a router and DHCP server. I'm replacing it, and would like to minimize down time.
If I unplug it, and plug in a different device with the same IP, will all the PCs with DHCP leases keep on working? (I have DHCP Conflict detect on, so it shouldn't reassign a DHCP address already used).
What if I want to change the IP (new subnet) - is there anyway to tell all the clients (Windows PCs) to release their DHCP leases and request new ones in a minute?
If before unplugging the old device, I have it release all DHCP leases, will the Windows PCs automatically ask for new DHCP addresses?
