Domain Lookup: registration, expiry dates & DNS records for any list of domains

Look up hundreds of domains at once: registrar, creation date, expiry date and days until expiry, status, nameservers, DNSSEC, whether the domain is available, plus A, AAAA, MX, NS, and TXT DNS records.

• Official registry data: uses RDAP, the modern structured replacement for WHOIS, straight from each domain registry. No scraped WHOIS text to parse.
• Paste anything: apify.com, www.example.org, or full links. They're cleaned and de-duplicated.
• DNS in the same row: see the hosting provider (A/AAAA), email provider (MX, e.g. Google Workspace), and verification records (TXT)
• No personal data: only the registrar's name. Owner contact details are never collected.

FAQ

Is this WHOIS? It's RDAP, the official successor to WHOIS run by the same registries, with structured and consistent data. Which endings work? More than 1,200, including .com, .net, .org, .dev, .app, .ai, .uk, and .co.uk. A few registries (e.g. .io, .co) don't offer RDAP yet. Those return DNS only, at no charge. Is "available" guaranteed? It means the registry has no record of the domain. Check with a registrar before buying, since some names are reserved or premium.

Data source and responsible use

Data comes from the registries' official RDAP services (the successor to WHOIS) and public DNS. Registrant contact details are never returned. Use it in line with the registries' terms and your local laws.
