digga helps developers, security researchers, sysadmins and curious users understand the infrastructure behind any domain.
Instead of jumping between separate DNS, WHOIS, RDAP, subdomain and email security tools, digga combines the most important domain research data in one simple interface. Enter a domain, subdomain or URL and get a structured overview of registration data, nameservers, DNS records, subdomains, IP ownership, ASN information and email authentication signals such as SPF, DKIM, DMARC, MTA STS, TLS RPT and BIMI.
digga is useful for debugging deployments, checking domain setups, investigating infrastructure, reviewing email security and quickly understanding who operates the systems behind a domain.
The project is free to use, open source and does not require an account.
