I have a router that runs on /24 network. Due to expansion, the 254 IP addresses is almost used up. I have a plan to create a /23 network for 510 IP address. But I need help for a better solution as my Idea will affect all the servers running on the .255.0 subnet mask. If having another subnet created with internal route so as not to temper with the existing network is possible, Please I need the steps to achieve this. Kindly waiting for responses.
