IPCONFIG.EXE is a new utility included with Windows. The purpose of this utility is to provide the user with diagnosticinformation related to TCP/IP network configuration. IPCONFIG also acceptsvarious Dynamic Host Configuration Protocol (DHCP) commands, allowing asystem to update or release its TCP/IP network configuration.
/?: Displays this help message. /all: Displays full configuration information. /release: Releases the IP address for the specified adapter. /renew: Renews the IP address for the specified adapter.
With no parameters, IPCONFIG will display only the IP address, subnet maskand default gateway for each adapter bound to TCP/IP.
With the /all switch, IPCONFIG will display all the current TCP/IPconfiguration values including the IP address, subnet mask, defaultgateway and Windows Internet Naming Service (WINS) and DNS configuration.
If adapter name is not specified with either the /Release or /Renewswitch, then the IP address leases for all adapters bound to TCP/IP willbe released or renewed.
NOTE: The /Release and /Renew switches can only be used on a system thatis configured with DHCP.
