/all: Displays full configuration information.
/release: Releases the IP address for the specified adapter.
/renew: Renews the IP address for the specified adapter.
With the /all switch, IPCONFIG will display all the current TCP/IP configuration values including the IP address, subnet mask, default gateway and Windows Internet Naming Service (WINS) and DNS configuration.
If adapter name is not specified with either the /Release or /Renew switch, then the IP address leases for all adapters bound to TCP/IP will be released or renewed.
NOTE: The /Release and /Renew switches can only be used on a system that is configured with DHCP.
