Hi yoofus,
Nice information.You can change your network IP address by this way,
If it is static IP,you cannot change it.Static IP will not change even when you reset the modem.You have to contact your Internet Service provider(ISP) for changing static IP.If your IP address is dynamic,it will change whenever you reset the modem.Before or after changing your IP address,you can check it using http://www.ip-details.com/ .
