There is a software Name : IP Mailer v2004 Program Description : If your ISP gives your computer, or your router/gateway, a dynamic IP (Internet Protocol) address that changes from time to time, you can email your IP address automatically to your friends and office/home so that you can find your computer for remote access regardless of the constantly changing IP address. If you use your computer remotely or need to have other people access some server functionality on your PC you can let them know what your IP address is automatically when it changes by letting IP Mailer handle the situation. IP Mailer constantly monitors your IP, and once you connect with your modem or your IP changes for some other reason, IP Mailer will detect it automatically. IP Mailer can also additionally send you the IP address once a day, whether it has changed or not. For More Information : http://ipmailer.wappu.tv/ Hope, this is the software u want.........
