Dynamic host configuration protocol (DHCP) is a service offered by most routers. The router assigns addresses to each computer that boots on the network. This makes it easy for network administrators to assign addresses, so users can simply boot the machine without requiring the administrator to edit the computer's settings. The administrator can view the routing table from any computer on the network using the Windows command prompt.
Click the Windows Start button and select "Run." Enter "cmd" into the text box and click the "Ok" button to open the Windows command prompt.
Enter "route print" into the command prompt and press the "Enter" button. Several IP addresses and router data are displayed.
View the data listed under "Router Table." This information is a list of IP addresses and network card interfaces configured on the router.
If you have more than one router enabled on the network, you can distinguish each router table using the "Gateway" column. The "Gateway" column is the router's IP address.
