What is Ipconfig?

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.

What is Ipconfig?

When you type ipconfig at a command prompt, the following information is displayed for each NIC:

  • IP address
  • Subnet mask
  • Default gateway

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.
