Whenever an internet connection is established through the RAS Dialup, usually the ISP assigns a temporary IP address to the calling PC. Using this unique IP address the PC can communicate with the outside world and can also be used to act as a Server by publishing this IP address to Clients. In some cases, the ISP assigns a Fixed or Permanent IP address to the calling PC which does not change on each connection to the internet. A fixed IP Address is much desired by Network users, but the service also comes with a fee with certain ISP's. Your PC's IP address can be compared to your Telephone number, people who know it can easily contact you when available.Component features:Notification of Active RAS Connection to the Internet.
