Ipconfig

Ipconfig

This diagnostic command displays all current TCP/IP network configuration values. This command is of particular use on systems running DHCP, allowing users to determine which TCP/IP configuration values have been configured by DHCP.

ipconfig [/all | /renew [adapter] | /release [adapter]]

Parameters

all

Produces a full display. Without this switch, ipconfig displays only the IP address, subnet mask, and default gateway values for each network card.

/renew [adapter]

Renews DHCP configuration parameters. This option is available only on systems running the DHCP Client service. To specify an adapter name, type the adapter name that appears when you use ipconfig without parameters.

/release [adapter]

Releases the current DHCP configuration. This option disables TCP/IP on the local system and is available only on DHCP clients. To specify an adapter name, type the adapter name that appears when you use ipconfig without parameters.

With no parameters, the ipconfig utility presents all of the current TCP/IP configuration values to the user, including IP address and subnet mask. This utility is especially useful on systems running DHCP, allowing users to determine which values have been configured by DHCP.
