the simplest thing would be to check if the value is anything other than "0.0.0.0" && if so to add a line below "MAC Address" w/something like "IP"
ideal situation would be to look up default admin/password based on the vendor && print a line that says something like, "if you log onto this network, try visiting ${IP} and using ${username} and ${password}" ...something like that, should also make sure not to be advising anyone to do anything illegal of course
