Note: The PrefixLength parameter specifies the subnet mask for the IP address. In this example, the PrefixLength of 24 equals a subnet mask of 255.255.255.0. To change the existing static IP value with PowerShell, use the cmdlet Set-NetIPAddress. For example, Set-NetIPAddress -InterfaceIndex 12 -IPAddress 192.168.0.1 -PrefixLength 24

Subnet Mask is made by setting network bits to all "1"s and setting host bits Aside from what others have said about the new subnet mask. 1. double check every switch, router, firewall (nat translations, routng rules, interface/port definitions), server, printer, or device that has a static IP address prior to making the change, identifying each device that will need to have their subnet changed. Hi Brett, thanks for the response. I have 155+ devices (90+ Light switches/outlets, 40 security/landscape devices and the rest are wired connections for xbox, computers). During the holidays devices that require an ip address goes up. As you can imagine I am juggling to keep it within range. Not sure why the ability to change the subnet mask is - it matters the order in which you change the mask. Be sure to change the mask on the router interface before you change the mask on any of the end stations. - if you are running a dynamic routing protocol be sure that it will accept, process, and advertise the /23 mask. - when you change the mask on the router it will introduce some mismatch
