WWIP (Watch WAN IP) Download
Watch WAN IP is intended to allow users to monitor the external IP address of their firewall/router connected to the Internet.
Many broadband providers assign IP addresses by DHCP rather than assigning static IP addresses. While these DHCP addresses might not change frequently, if/when they do change, it can cause you to be unable to connect to your home network/computers remotely.
Watch WAN IP works by "Screen Scraping" the IP address off of your router and comparing it to the old address. This means that the program will connect to the router to get the HTML source of the configuration page the WAN IP is displayed on. Then, using parameters you define, locates and extract the IP address from the HTML source. If the IP has changed, it will notify you.
