ipconfig
(standing for 'Internet Protocol configuration') is a console application program of some computer operating systems that displays all current TCP/IP network configuration values and refreshes Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS) settings.[1]ipconfig
command supports the command-line switch/all
. This results in more detailed information than ipconfig
alone.ipconfig
is to force refreshing of the DHCP IP address of the host computer to request a different IP address. This is done using two commands in sequence. First, ipconfig /release
is executed to force the client to immediately give up its lease by sending the server a DHCP release notification which updates the server's status information and marks the old client's IP address as 'available'. Then, the command ipconfig /renew
is executed to request a new IP address.[3][4] Where a computer is connected to a cable or DSL modem, it may have to be plugged directly into the modem network port to bypass the router, before using ipconfig /release
and turning off the power for a period of time, to ensure that the old IP address is taken by another computer.[5]/flushdns
parameter can be used to clear the Domain Name System (DNS) cache to ensure future requests use fresh DNS information by forcing hostnames to be resolved again from scratch.[6]ipconfig
in Mac OS X serves as a wrapper to the IPConfiguration agent, and can be used to control the Bootstrap Protocol and DHCP client from the command-line interface.[7] Like most Unix-based operating systems, Mac OS X also uses ifconfig
for more direct control over network interfaces, such as configuring static IP addresses.Wikibooks has a book on the topic of: Guide to Windows Commands |
