Ipconfig (sometimes written as IPCONFIG) is a command line tool used to control
the network connections on Windows NT/2000/XP machines. There are three main
commands: "all", "release", and "renew". Ipconfig displays all current
network configuration values and refreshes Dynamic Host Configuration Protocol (DHCP)
and Domain Name System (DNS) settings. Used without parameters, ipconfig
displays the IP address,
subnet mask, and default gateway for all adapters.
