Static IP address on Installation

I am having some issues trying to assign a static IP address on installation (I know it can be changed after installation) as it seems that the installation screen are first asking for netmask in the format and then an ip address . I will see if I can capture a screen as a picture might help explain better

So sorry just re-read and its the ip subnet first not netmask …
