Greetings! I just started working for a company that has been seeing a bit of growth over the past year, and our DHCP server is running out of IPs to assign on an almost daily basis (which I've temporarily remedied by reducing lease time). I am looking for the quickest and most painless way of increasing the number of IPs available on the network, and, through my reading, have narrowed it down to configuring a superscope or supernet.
The existing network its 192.168.2.0 /24 and my original plan was to change the subnet mask to /23 to allow for 192.168.2.1-255 and 192.168.3.1-254 IPs to be assigned through DHCP. I know that the subnet mask would need to be changed to 255.255.254.0 in the router/gateway and my DHCP, DNS and other servers.
However, as I have been looking things over on the network, I am realizing just how many workstations, printers and other devices have statically assigned IPs. My biggest question now is: Will I have to go around to each and every device on the network with a static IP and change the subnet mask in order for these devices to still communicate on the network, or will they still be able to communicate as long as the router/servers mask have been updated and their IPs stay the same, within the original IP range?
I was thinking that, if it is necessary to go to each and every device and update the subnet mask, that maybe creating a superscope would be an easier option. But then I am thinking that all of the servers and network printers and such would need to be able to be configured with a second IP addess?
Any help/suggestions would be most appreciated.
