Ipconfig command:
Ipconfig command displays all current TCP/IP network configuration values. When we use simple ipconfig command without any parameters then its display the IP address, subnet mask, and default gateway for all adapters. We can also use Ipconfig command with different parameters which are:

/all : Displays the full TCP/IP configuration for all adapters.

/renew [Adapter] : Renews DHCP configuration for all adapters (if an adapter is not specified) or for a specific adapter if the Adapter parameter is included. This parameter is available only on computers with adapters that are configured to obtain an IP address automatically.

/release [Adapter] : Release the current DHCP configuration and discard the IP address configuration for either all adapters or for a specific adapter.

Syntax

ipconfig [/all] [/renew [Adapter]] [/release [Adapter]] [/flushdns] [/displaydns] [/registerdns] [/showclassid Adapter] [/setclassid Adapter [ClassID]]
