Checking TCP/IP Network Settings with IPCONFIG

If you’re connected to a TCP/IP network, the IPCONFIG utility is one that you need to be familiar with. Most users are familiar with the tool from using it to renew an IP address allocated by a DHCP server via the /renew switch. However, IPCONFIG provides a wealth of useful information about your system’s TCP/IP settings, especially when the /all switch is issued. This command will display information about the state of your connection, whether DHCP is being used, the IP address, subnet mask, and default gateway configured on your system, and more.
