Change the DHCP Lease Time Tap on the + button on the Network Settings box to expand the card, then tap the LAN Settings link. Tap on LAN DHCP Lease Time link. Enter the desired time in the field below Set Lease Time. By default, it is set to 1440 minutes (24 hours).

It isn't possible to change the DHCP lease time in your device's network settings as this is controlled by the DHCP server that allocates IP addresses, which is usually your network router. You'll need to have administrative access to your router to change this.

Next, if you want to renew the DHCP lease time of your Windows 10 PC, run the following command in Command Prompt or PowerShell: ipconfig /release | ipconfig /renew. Wait for the command to do its job and, when it finishes, it should display some information about your network adapters.

In the Command Prompt, type ipconfig /release and press Enter. If the command was successful, type ipconfig /renew and press Enter.

Short DHCP lease time has some advantages, especially for networks that have a high turnover of devices or a limited pool of IP addresses. For example, if you have a public Wi-Fi network that serves many visitors, you may want to use a short lease time to free up IP addresses quickly and avoid running out of them.

DHCP lease can be either terminated by user or network administrator, or it may expire. Lease termination may be forced when the DHCP server is changed. On Windows termination is done from Command Prompt by using ?ipconfig /release? command.

To disable the DHCP server feature in the router: Launch a web browser from a computer or mobile device that is connected to your router's network. Enter the router user name and password. ...

In short, by selecting the longest DHCP lease time possible, you can reduce the odds of a device having its IP address changed. A lease that never expires is ideal, but even extending the lease time from a day to a week reduces the number of potential address changes from 365 to 52.

Since the default DHCP address range is between 100 and 149, you'll want to avoid all of the addresses between 192.168. 1.100 and 192.168. 1.149 when you're assigning static IP addresses. That leaves the ranges from 2-99 and from 150-254 wide open, which is usually plenty for most home networks.
