text: how do you change your ip? i have a cable modem, and i called my isp, and they told me they dont give out ips.  i went into the command prompt.  and i put ipconfig/release and then ipconfig/renew.  however the same ip address does not change.  it stays the same.  when you look up my ip, it is resistering 125 miles from my location.  help,  thanks it is because your service providers dns servers know your mac address and assign the same ip again.  try to reconnect after certain hours... it might work
