Your computer’s IP address can be either static or dynamic. A static IP address is when a specific IP address has been assigned to a specific computer on the local network. A dynamic IP address is automatically or dynamically configured by the DHCP server. Whenever possible I recommend using a dynamic IP address with DHCP, if your network supports it. If you use a dynamic IP address with DHCP then you don’t have to change your settings if you move your computer to another location, and DHCP doesn’t require you to manually configure settings such as Domain Name System (DNS) and Windows Internet Name Service (WINS). To change your IP address in Windows 7 do the following:
1. Click the Start Orb
