My Two Cents, By Archie Tucker

Everything on your network has an IP address (Internet Protocol address), a unique identifier for each device, and is often needed during support issues. An IP address can be either dynamic or static. A static IP address doesn’t change. We normally setup your SonicWall, servers and printers using static IP addresses. Dynamic IP addresses are issued using a leasing system, which is normally maintained by your SonicWall. A dynamic IP address can change. To get your PC’s LAN IP address, you can use the ipconfig command from the DOS command prompt (instructions to access the DOS prompt). A LAN (Local Area Network) is a type of network, like the network in your office, the internet is a good example of a WAN (Wide Area Network). To get your WAN IP, you can enter www.whatismyip.com from your web browser. Normally, you would have a static WAN IP at your office (additional charge for static IP address) and a dynamic IP at your home.
