Other versions of this page are also available for the following:

This is a command-line utility that prints out the TCP/IP-related configuration data of a host.

IPConfig supports IPv6. For more information about IPv6, see Core Protocols of IPv6 and IPv6 Addressing.

The syntax for the IPConfig utility is as follows.


[ /d | /? | /all | /release [adapter index] | /renew [adapter index] ]
/d

Redirects the output to the debug output port.

/?

Displays a help message that shows the syntax and describes the options for IPConfig.

/all

Displays full configuration information.

/release

Releases the IP address for the specified adapter.

/renew

Renews the IP address for the specified adapter.

adapter index

Specifies the index of the adapter for which you want to release or renew an IP address.

If you use the IPConfig utility without any options, IPConfig displays by default only the IP address, subnet mask, and default gateway for each adapter bound to TCP/IP.

The following example shows typical output produced by the IPConfig utility.
