Control Link Lease For Free

For a home network, the default 24 hours (1440 minutes or 86400 seconds) is fine. The amount of devices in a home network is limited, maybe up to 3 per household member where your pool of IP addresses is around the 200 addresses. But a higher lease time of 8 days would work evenly good.

The default lease time for the DHCP server is 24 hours. When setting the lease time on your DHCP server, consider your goals, usage patterns of your site, and service arrangements for your DHCP server.

Typically, the DHCP lease time default setting on most servers is 24 hours. However, this may be shorter or longer depending on your own server. Settings can be adjusted from one minute up to a certain number of days. You'll want to avoid setting the lease time too low as this can cause interruptions to service.

If your network topology rarely changes and you have enough IP addresses in your address pool, you can configure DHCP to use infinite leases, that is, leases that never expire. However, infinite leases are not recommended. If you use an infinite lease, the IP address is leased to the client indefinitely.

Now, here is the tutorial. Open Run dialog. Type dhcpmgmt. ... Open the properties of the DHCP scope for which you want to change the lease time. Under the Lease duration for DHCP clients section, choose General tab. Then input a new lease time in the Limited to field. Then click OK to save your changes.

When the lease expires or a client logs out and releases its IP address, the server reclaims the IP address, which can then be allocated to other clients.

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.
