The ipconfig.exe is an external command and is available in Microsoft operating systems. The purpose of this utility is to provide the user with diagnostic information related to TCP/IP network configuration such as all current TCP/IP configuration values. It also accepts various DHCP commands, allowing a system to update or release its TCP/IP network configuration.
This command can be utilized to verify a network connection as well as to verify the network settings and it displays the current IP address, as well as its subnet and gateway addresses.
The ipconfig command is the command-line equivalent to the winipcfg command, which is available in Windows Millennium Edition, Windows 98, and Windows 95. Although Windows XP does not include a graphical equivalent to the winipcfg command, you can use Network Connections to view and renew an IP address.
The syntax for Ipconfig.exe is:
ipconfig [/? | /all | /release [adapter] | /renew [adapter] | /flushdns | /registerdns]
| /? | 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 | Purge the DNS resolver cache |
| /registerdns | Refresh all DHCP leases and re-register DNS names |
| /displaydns | Display the contents of the DNS resolver cache |
With no parameters, IPCONFIG will display only the IP address, subnet mask and default gateway for each adapter bound to TCP/IP.
