There may come a time when you are setting up your network that you may need to release and renew your IP address in order to obtain a new one from your DHCP enabled device. For example if you just installed a DSL/Cable router and use DHCP from the router to get an IP Address you may need to release the IP address from your internet provider to obtain a new one from your router.
To perform this process do the following:
1. Click on Start.
2. Then click Run.
3. Type winipcfg in the box and click Ok. A window will then appear on the screen. The IP Address field shows the current IP address for the default network adapter.
4. If the computer is holding a current IP address, click the Release button to have it let go of this address.
5. Then click the Renew button to obtain a new IP address.
Note:
For Windows 2000/XP/2003 all you need to do is open a command prompt and type in ipconfig /release <enter> and then ipconfig /renew <enter>.
