About:
ddclient is a Perl client used to update dynamic DNS entries for various DNS providers. It automatically detects the machine's public IP address changes and updates the corresponding DNS records, ensuring consistent remote access. This makes it an essential tool for maintaining reliable connectivity to devices behind dynamic IP addresses.

Key Features:

Supports a wide range of DNS providers and protocols
Automatically detects public IP changes via routers or web services
Can run as a daemon, from cron, or as a systemd service
Configurable update intervals and failure handling

Use Cases:

Hosting a personal web server or game server on a home internet connection
Maintaining a stable VPN endpoint for remote work
Accessing home automation or NAS devices remotely

Alternatives:

inadyn – A lightweight C-based alternative with similar functionality and provider support.
Cloudflare Dynamic DNS – Cloudflare's native solution, but requires specific API token configuration and is provider-locked.

License: GPL-2.0-or-later

Dependencies: openssl@3

Bottles available for: arm64_tahoe, arm64_sequoia, arm64_sonoma, sonoma, arm64_linux, x86_64_linux

Important Notes:

For ddclient to work, you will need to customise the configuration
file at `$HOMEBREW_PREFIX/etc/ddclient/ddclient.conf`.

Note: don't enable daemon mode in the configuration file; see
additional information below.

The next reboot of the system will automatically start ddclient.

You can adjust the execution interval by changing the value of
StartInterval (in seconds) in /Library/LaunchDaemons/homebrew.mxcl.ddclient.plist.
