A TCP/IP utility that displays the current TCP/IP configuration settings for each network interface card (NIC) on a Microsoft Windows NT or Windows 2000 system.

When you type ipconfig at a command prompt, the following information is displayed for each NIC:
You can display additional information, including the host name, physical address, and Dynamic Host Configuration Protocol (DHCP), Windows Internet Name Service (WINS), and Domain Name System (DNS) configuration, using ipconfig /all.
You can release and renew IP addresses obtained by DHCP using ipconfig /release and ipconfig /renew.
