If you want to learn more about IP addresses, then please read this article. First and foremost, what are IP addresses? In fact, they are simply just some logical addresses of network adapters. Now, why do you need IP addresses? A primary reason is to help you to join the Internet Protocol networks. Basically, IP addresses are required as creating an online business. These addresses are the basis for your computers to identify themselves on-line in addition to computer networks. Typically, a home network router will consist of two IP addresses, one being the internal home (LAN) while the other being the external Internet (WAN). Generally, the default internal IP address will be stated in documentation. However, the administrators have the right to change or edit the internal IP address during the router setup, which will eventually be fixed once set. The LAN IP address will be displayed from the router's administrative console. Conversely, the external IP address or WAN IP address will be set once the router connects to the Internet service provider. For your information, home broadband routers will have their own default internal LAN IP addresses. For example, Linksys routers use 192.168.1.1 while other US Robotics routers use 192.168.123.254. These internal addresses are determined by the manufacturer, which will also be changed or edited using the network router's administrative console upon the administrator's request. The internal IP address like 192.168.1.1 is really a private IPv4 network address. Any specific network router and any computer on a local network can be set to this IP address. Nevertheless, only one device is allowed to use this IP address in the old days to prevent IP address conflicts. Consequently, either one computers will be unusable for network operations.
