What is DHCP Lease Time?

DHCP (Dynamic Host Configuration Protocol) lease time refers to the duration during which a device is assigned an IP address from the DHCP server. Once the lease time expires, the device must request a new IP address. Adjusting this lease time can help manage network resources more effectively, especially in environments with frequent device connections and disconnections.

How to Modify DHCP Lease Time

Changing the DHCP lease time involves accessing your router's settings. Here is a step-by-step guide to help you modify the lease time:

1. Log into Your Router

Open a web browser and enter your router’s IP address, commonly 192.168.0.1 or 192.168.1.1. Enter your username and password. If you haven't changed these, they might still be the default, often found on a sticker on the router.

2. Navigate to the DHCP Settings

Look for a section labeled DHCP or Network settings. This section will typically include options for managing IP addresses, including the lease time.

3. Find the Lease Time Setting

Within the DHCP settings, you should see an option labeled Lease time or Address lease time. This is where you can adjust the duration of the lease.

4. Change the Lease Time

Enter your desired lease time. A common default is 24 hours (1440 minutes), but you can set it to a shorter or longer duration based on your needs. For example, if you want to reduce the lease time to 12 hours, set it to 720 minutes.

5. Save Your Changes

After adjusting the lease time, make sure to save or apply the changes. Your router may reboot automatically. Consult your router's manual if you need specific instructions for saving settings.

6. Test the Settings

To ensure the changes took effect, you can check the DHCP clients list on your router or restart a device to see if it receives a new lease with the updated time. This will confirm that the changes have been applied successfully.

Notes and Considerations

The exact steps may vary depending on the router model. It's always a good idea to consult your router's manual or manufacturer's website for specific instructions if needed. Adjusting the lease time can impact how devices connect to your network, especially in environments with many devices. Carefully consider your network's needs when making changes.
