## Project history and usage

dug is a .NET CLI for checking DNS propagation from multiple resolvers and presenting the results in pretty or machine-readable formats. It is a niche networking tool aimed at the moment after DNS changes, when operators want to see how records look around the world.

### Project history

The public release history visible on GitHub starts in January 2021. The README states that the GitHub repository is a mirror of the primary Unfrl repository and marks the project as unmaintained, while still documenting usage, localization, packaging, Docker images, and .NET development.

The tool's stated goal is to make DNS propagation checks easy, with templated output for scripts and monitoring. Release activity continued through 2024, ending at least publicly with the 0.0.94 release in October 2024.

### Adoption history

dug's adoption appears narrow but real: its README documents Homebrew installation for macOS and Linux, AUR availability, Docker images, and platform binaries. The Homebrew formula keeps it visible to users who want a DNS propagation checker without manually downloading .NET binaries.

### How it is used

Typical use is running dug against a domain after changing DNS records, optionally selecting record type, choosing server counts, or emitting JSON and templated fields for scripts. This makes it closer to a propagation dashboard in a terminal than to a direct dig replacement.

### Why package nerds care

dug is package-nerd interesting because it packages a web-style DNS propagation checker as a local CLI. It also shows a less common Homebrew shape: a .NET single-file networking utility with internationalized output and scripted JSON modes.

### Timeline

- 2021: 0.0.60 release appears in the public GitHub release history.
- 2022: 0.0.90 released after many small 0.0.x increments.
- 2023: 0.0.92 released.
- 2024: 0.0.94 appears in the public GitHub release history.

### Related projects

- dig, drill, and dog are related DNS CLIs, but dug focuses on propagation checks across resolvers.
- Web DNS propagation checkers are the closest product-style comparison; dug brings that workflow into the terminal.
