DHCP Release on Mac OS - Shell/Bash

Introduction

As a programmer, you may need to release your DHCP lease on Mac OS for some reason. This can be easily achieved using the built-in Terminal and Shell/Bash commands.

DHCP Release Command

To release your DHCP lease on Mac OS, follow these steps:

1. Open Terminal on your Mac OS.
2. Type the following command and press Enter:

sudo ipconfig set en0 NONE

3. Enter your administrative password if prompted.
4. Your DHCP lease will now be released.

Explanation

The above command essentially sets the interface en0 to have no IP address, which will cause the DHCP client to release its lease. You can replace en0 with the name of your specific interface if needed.

Alternatively, you can use the following command to release your DHCP lease without affecting your network interface configuration:

sudo ipconfig set <interface> DHCP

This command will force the DHCP client to release and renew its lease on the specified interface.

Conclusion

In conclusion, releasing your DHCP lease on Mac OS is a simple and straightforward process, which can be achieved using Shell/Bash commands on the Terminal. Make sure to only release your lease if you have a good reason to do so, as it may cause disruptions to your network connection if done unnecessarily.
