IPConfig ipconfig utility and its equivalent graphical user interface - WinDows 95/98 WiniPCFG can be used to display the current TCP / IP configuration settings. This information is generally used to verify that manually configured TCP / IP settings is correct. However, if your computer and the local area network use the dynamic host configuration protocol (Dynamic Host Configuration Protocol, DHCP - Windows NT assigns less IP addresses to more hosting protocols, similar to dial-up Internet access Dynamic IP assignment), the information displayed by this program may be more practical.
USAGE: ipconfig [? / | / All | / renew [adapter] | / release [adapter] | / flushdns | / displaydns | / registerdns | / showclassid adapter | / setclassid adapter [classid]] where adapter Connection name (wildcard characters * ? and allowed, see examples) Options:?... / Display this help message / all Display full configuration information / release Release the IP address for the specified adapter / renew Renew the IP address for the specified adapter / flushdns Purges the DNS Resolver cache. / registerdns Refreshes all dHCP leases and re-registers DNS names / displaydns Display the contents of the DNS Resolver Cache. / showclassid Displays all the dhcp class IDs allowed for adapter. / setclassid Modifies the dhcp class id. The default is to display only the IP address, subnet mask and default gateway for each adapter bound to TCP / IP. for Release and Renew, if no adapter name is specified, then the IP address leases for all adapters bound to TCP / IP will be released or renewed. For setClassID, IF NO CLA SSID IS Specified, THE CLASSID IS Removed. Examples:> ipconfig ... show information.> ipconfig / all ... show detailed information> ipconfig / rent ... renew all adapters> IPConfig / Renew EL * ... Renew Any Connection That Has ITS Name Starting with el> ipconfig / release * con * ... release all matching connections, eg. "Local Area Connection 1" or "Local Area Connection 2" IPConfig - No parameters when using ipconfig Option, then display IP address, subnet mask, and default network values ipconfig / all, IPConfig can display it configured and used when using all options. Additional information (such as IP addresses, etc.), and display the physical address (MAC) built into the local network card. IPConfig / Release and IPConfig / Renew - This is two additional options that can only work on a computer that leases its IP address to the DHCP server.
