## What it is
In-a-Dyn is a small Dynamic DNS (DDNS) client written in C that keeps DNS hostnames in sync with a changing public IP address, with HTTPS support and plugins for many DDNS providers. It is commonly bundled in GNU/Linux distributions and embedded routers and supports multiple host records and custom providers.

## Use cases
- keep a home server's domain name pointing at a changing ISP IP address
- update DDNS records on a router or gateway automatically
- maintain multiple hostnames with the same public IP
- run a web server behind a dynamic IP connection
- configure custom DDNS providers via HTTP(S)
- detect IP changes on backup/redundant internet connections

## When to choose
- you need a lightweight, scriptable DDNS updater on Linux or embedded systems
- your DDNS provider is one of the many supported services (FreeDNS, DynDNS, etc.)
- you want a daemon that updates DNS records on IP change with HTTPS

## When to avoid
- the project was archived in October 2025 and is no longer maintained
- you need guaranteed upstream security updates for a long-lived deployment
- you want a GUI-managed DDNS solution
