Below are two different methods of how this can be done at the command line.
ifconfig eth0 down
Running the above command would take the eth0 interface (the first network card) down. Which is the same as releasing the IP address from that network card.
ifconfig eth0 up
After the interface is taken down, typing in the above command would bring that interface back up.


or
dhclient eth0

How do you release and renew an ip address?

In Windows operating systems, open a command prompt and type "ipconfig /release," which dumps the automatic address it had, and then "ipconfig /renew," which gets a new address, which will be in the address space that you just changed the router to. Of course you won't type the quotes, and depending on which Windows version you have you may need to make it "release all" and "renew all." For Mac OS, either restart your computer, or go to the Apple menu, choose System Preferences, choose Network from the View menu, and then Active Network Ports from the View menu. Deselect the "ON" checkbox for your network adapter, click on Apply, then reselect the "ON" checkbox and click Apply again. Finally you can check your new ip address at IP-Details.com

Purpose of the ipconfig release command?

What is the purpose of the ipconfig /release command? The ipconfig /release command forces a client to give up its current IP address. The IP Release command releases the "hold" of any IP address configuration data it has received from the DHCP server and allows that IP Address to be re-assigned to another network adapter. After issuing a release command, your network adapter will no longer have a valid configuration and will not be able to connect to the network unless you use the command ipconfig /renew or you restart the adapter/computer.

What is the correct way to use protocol ipconfig in a windows 2000 environment?

H:\> IPCONFIG /? Windows 2000 IP Configuration USAGE: ipconfig [/? | /all | /release [adapter] | /renew [adapter] | /flushdns | /registerdns | /showclassid adapter | /setclassid adapter [classidtoset] ] adapter Full name or pattern with '*' and '?' to 'match', * matches any character, ? matches one character. 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 class id is specified, then the classid is removed. Examples: > ipconfig ... Show information. > ipconfig /all ... Show detailed information > ipconfig /renew ... renew all adapaters > ipconfig /renew EL* ... renew adapters named EL.... > ipconfig /release *ELINK?21* ... release all matching adapters, eg. ELINK-21, myELELINKi21adapter.
