The TCP/IP Guide - TCP/IP Configuration Utilities (ipconfig, winipcfg and ifconfig)

You can see from the list of options in Table 308 that most of the non-viewing uses of ipconfig are actually related not to configuring a host but rather controlling the operation of protocols such as DNS and DHCP. One common use of ipconfig is to force a host to seek out a new DHCP lease, which an be done using “ipconfig /release” followed by “ipconfig /renew”.
