A private IP address hides you behind your ISP’s server providing an extra layer of security; however, private IP addresses keep you from using Web services that require an IP address to communicate with you. For instance, if you want to host your own website, a private IP will make your site invisible to users surfing the Internet. Also, IP-based websites that feature chats, P2P, games or enable you to send and receive files will not function correctly with a private IP address. A public IP address will fix these problems because you become visible on the World Wide Web. Writer Bio
