Force a LAN DHCP lease to renew

If your having issues with an existing lease, perhaps an ip conflict... and you want to force your windows DHCP client to get a new IP address then try the following:
  1. ipconfig /release
  2. reboot
This has worked for me on Windows 7, so it probably works on recent windows versions too.

A simple ipconfig /release and ipconfig /renew doesn't cut the mustard in most cases...

No idea if this would work for a WAN lease, worth a try I guess.

Good post...To change the WAN IP if you are having a Static IP then you need to request for a new IP from your ISP.If you are having a Dynamic IP then you can reset the modem(switch it OFF and ON) and this will generate a new one.You can check for the change by visiting
Ip-details.com and confirm it.
