You need to find out more about IP addresses, then please read this article. Above all, what are IP addresses? In fact, they are simply just a set of logical addresses of network adapters. Now, why do you really need IP addresses? The reason is to assist 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 over the internet 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 can be viewed from the router's administrative console. On the flip side, 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 can 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 actually a private IPv4 network address. Almost any 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 previously to prevent IP address conflicts. Because of that, either one or both computers will be unusable for network operations.
