How to use the command `dhcp6d` (with examples)

The dhcp6d command is a stateless DHCPv6 server that allows for the allocation of IPv6 addresses to clients on a network. It is typically used in conjunction with the InternetSharing service. It is important to note that dhcp6d should not be invoked manually, and more information about its usage can be found at https://www.manpagez.com/man/8/dhcp6d/ .

Use case 1: Start the daemon

Code:

dhcp6d

Motivation: The dhcp6d command is used to start the daemon, allowing it to allocate IPv6 addresses to clients on the network.

Explanation: This command simply starts the dhcp6d daemon without any additional arguments or configuration. Once the daemon is running, it will begin responding to DHCPv6 requests from clients.

Example output:

DHCPv6 server started successfully.

Use case 2: Use a custom configuration

Code:

dhcp6d path/to/config_file

Motivation: The dhcp6d command can be used with a custom configuration file to specify settings and options for the DHCPv6 server.

Explanation: By providing the path to a custom configuration file as an argument to the dhcp6d command, the server will use that configuration instead of the default settings. The configuration file contains various options, such as lease times, ranges of IPv6 addresses to allocate, and additional DHCPv6 options.

Example output:

DHCPv6 server started using custom configuration file: path/to/config_file.

Conclusion:

The dhcp6d command is a powerful tool for managing and allocating IPv6 addresses on a network. By starting the daemon, you can enable DHCPv6 services, and by using a custom configuration file, you can tailor the server’s behavior to meet your specific requirements. Remember to consult the additional documentation for more detailed information on dhcp6d usage.
