Dug, A global DNS propagation checker on your CLI

In plain words

Dug is a command-line tool for checking DNS propagation across the globe. It allows developers to verify how DNS records have spread to nameservers worldwide, useful for troubleshooting domain configuration issues after updates. The tool runs locally in the terminal, making it accessible for developers who work primarily in command-line environments and need quick visibility into DNS changes across different geographic locations.

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself.
