How to Find a WAN Address

WAN is an abbreviation for the "wide area network" that is the same as the Internet. Each computer connected to the Internet has is a unique numeric IP address (WAN address) written in the dot-decimal form (e.g. 195.15.32.1). However, IP addressing within a local area network (LAN) is more complicated. LAN consists of a few computers within a limited area connected to the Internet via a router. The router assigns internal IP addresses to LAN computers that are different from their respective WAN addresses.
