Domain Lookup

Check a domain's DNS records (A, AAAA, MX, NS, TXT, CNAME, SOA, CAA) and its registration — registrar, dates and status.

How to use
  • Type a domain (or paste a full URL) and press Look up.
  • Registration shows the registrar, when the domain was registered and when it expires. Expiry within 30 days is highlighted.
  • DNS records lists A, AAAA, CNAME, MX, NS, TXT, SOA and CAA records with their TTL. Email security checks for SPF and DMARC, which stop others sending mail as your domain.
Good to know
  • Registration data comes from the registry over RDAP, the modern replacement for WHOIS. Personal contact details are usually hidden for privacy. Some country domains (such as .io) don't offer RDAP yet, so only DNS is shown for them. .th domains are looked up at THNIC.
  • DNS changes can take up to the TTL shown to reach everyone.
  • Lookups go through our server, which asks the registry and Cloudflare's public DNS for you. We don't store the domains you look up.
