The command ipconfig /? displays the set of available options. Ipconfig /all This option displays the same IP addressing information for each adapter as the default option. Additionally, it displays DNS and WINS settings for each adapter. Ipconfig /release This option terminates any active TCP/IP connections on all network adapters and releases those IP addresses for use by other applications. Ipconfig/release can be used with specific Windows connection names. In this case, the command affects only the specified connections, not all connections. The command accepts either full connection names or wildcard names. Examples: ipconfig /release "Local Area Connection 1"ipconfig /release *Local* Ipconfig /renew This option re-establishes TCP/IP connections on all network adapters. As with the release option, ipconfig /renew takes an optional connection name specifier. Both /renew and /release options only work on clients configured for dynamic (DHCP) addressing.
