ok heres my situation
I have a computer at home which has a dyndns set up to it and my isp keeps the same ip on my modem for around 45 days at a time so the dyndns stops working every 45 days or so.
I tried using a tool that updates dyndns but because the ip only changes every couple of months I have to log in and update it because they don't see any change in my ip. So today I just set it as a static ip address and started a hunt for software that is
Free, can check my ip, and
email me the ip when it changes
