Release and Renew an IP Address in Windows 8

About Releasing and Renewing an IP Address in Windows 8

Releasing and renewing dynamic IP addresses is a concept of Dynamic Host Configuration Protocol (DHCP) server. Releasing and renewing IP addresses means to replace the currently assigned dynamic IP address by obtaining a new one for the DHCP client computer.

When DHCP server assigns an address to a client computer for the first time, it provides the IP address for specific time, technically known as ‘lease duration’. As soon as 50% of the time of lease duration lapses, the client computer automatically sends a request to the DHCP server to renew assigned IP address.

However, in some organizations administrators might want to change their existing IP address scheme assigned by a DHCP server. In such cases, administrators must renew the previous IP addresses assigned to the client computers. To achieve this task, administrators must first release the current IP address using a command. Once this is done, another command must be executed to get a new IP address.
