Show HN: Digga – DNS, RDAP/WHOIS, subdomains and more in one lookup

- Digga is a new, free-to-use web tool that aggregates multiple kinds of domain intelligence — DNS records, RDAP/WHOIS ownership data, subdomain discovery, and more — into a single lookup interface. - DNS (Domain Name System) translates human-readable domain names into IP addresses; RDAP and WHOIS are protocols that reveal who registered a domain and when. - The project was featured on Hacker News ("Show HN"), a community where developers share side projects and early-stage tools for feedback. - Most existing tools (like SecurityTrails or whois.domaintools.com) either charge for comprehensive data or require switching between several services for different lookups. Digga aims to fill that gap with a free, all-in-one alternative. - Its value for technical readers: it simplifies reconnaissance for security research, OSINT (open-source intelligence), or debugging domain configuration.
