## Project history and usage

Inadyn, short for In-a-Dyn, is a small dynamic DNS client. It keeps DNS host records synchronized with changing public IP addresses, especially for home servers, routers, gateways, and redundant Internet connections.

### Project history

The Troglobit GitHub repository was created in 2010, while older provider documentation identifies inadyn as a C-based DDNS client written by inarcis. Troglobit's line modernized the project around HTTPS support, a libConfuse-based configuration format, provider plugins, systemd integration, and many service-provider examples.

A 2014 Troglobit release note described the project as reignited and pointed toward the 2.0 configuration format. The repository's GitHub releases show the 1.99.x bridge releases in 2014 and 2015, then a long 2.x line of DDNS provider additions and fixes.

### Adoption history

Inadyn's adoption is tied to appliances and distribution packaging. The project README and Troglobit project page both say it is common in GNU/Linux distributions and off-the-shelf routers and Internet gateways, which matches the batch metadata listing apk, Homebrew, Debian, Fedora, MacPorts, Nix, and Ubuntu packages.

### How it is used

Users place provider credentials, hostnames, and update policy in inadyn.conf. The daemon periodically or on demand checks the public address and updates one or more DDNS records through providers such as FreeDNS, Cloudflare-style APIs, and other supported services.

### Why package nerds care

For package people, inadyn is the archetypal tiny network daemon: one C program, one config file, one service unit, and decades of DDNS-provider churn encoded as package updates. It matters because it is often the glue that makes a dynamic residential or small-office connection reachable by a stable hostname.

### Timeline

- 2010: Troglobit GitHub repository created.
- 2014: v1.99.7 and v1.99.8 release notes described project revival, provider plugin work, HTTPS support, and the path toward 2.0.
- 2015: 1.99.x bridge releases continued on GitHub.
- 2020: Troglobit project page documented the common /etc/inadyn.conf layout and systemd service usage.
- 2025: GitHub repository archived after the 2.12.0 release line.

### Related projects

- inadyn-mt and inadyn-advanced are related DDNS-client forks documented by SourceForge and package metadata.
- ddclient, router firmware DDNS clients, systemd service units, and provider-specific DDNS APIs occupy the same operational space.
