Features

One lookup, full picture

Every check returns hosting provider, server location, DNS, SSL, and WHOIS data, all from a single query.

  • Hosting provider detection

    Find out if a site runs on AWS, Hetzner, Cloudflare, or another network, identified from the owner of its IP address and ASN.

  • Server geolocation

    See the country, city, and network behind any IP address. Useful for latency analysis and compliance checks.

  • SSL certificate details

    Check who issued a site's certificate, when it expires, which domains it covers, and which TLS version the server uses.

  • Full DNS breakdown

    Pull A, AAAA, CNAME, MX, NS, TXT, SOA, CAA, and SRV records in one lookup. No need to juggle separate dig commands.

  • WHOIS registration data

    See a domain's registrar, owner, registration and expiry dates, and DNSSEC status, straight from the registry over RDAP or WHOIS.

  • Developer-first API

    Integrate hosting lookups into your own tools with a REST API. JSON responses and API key auth.

  • Lookup history

    Sign in and every lookup you run is saved to your dashboard, with links back to the full results.

  • Standalone tools

    Need one piece of data? Use the free DNS lookup, IP lookup, SSL checker, or WHOIS lookup on its own.
