I am trying to install Ubuntu 18.04 LTS, when going through the installation it appears I can configure the network manually, when I attempt I run into the following issue while configuring the IPv4 settings

It wants the CIDR format for the Subnet, our Subnet is 255.255.255.0 so our CIDR should be 255.255.255.0/24 which it will accept. However it says our static ip address we are trying to assign which is 192.168.200.100 "is not contained in the 255.255.255.0/24". Which is confusing because all of our other machines and servers are on a 192.168.200.xxx configuration and working fine including an old 16.04 LTS server.

Can anyone help me troubleshoot this issue?

Thanks in aadvance

For the CIDR format netmask, will the installation accept, simply, /24?
