WHOIS Lookup

Get domain registration information including registrar, creation date, expiration date, and nameservers.

About WHOIS Lookup

This lookup reads public domain registration data through RDAP. Available fields can include the registrar, registration dates and nameservers. Registrant identity may be redacted or absent; a lookup is not proof of who currently controls a website.

Read how to read a WHOIS lookup for what each field means and why names are often redacted.

Planning a change? Prepare DNS before moving a domain, including the difference between registration, delegation and cached record values.

WHOIS names a domain registrar, not the company that carries your connection. Find out your ISP from your public IP, or look up the ISP for an IP address you already have. Registration data is also not a browsing log — what your ISP can see depends on the traffic path.

This lookup does not say whether your home line uses a shared public address. What CGNAT is, and how to tell if you are behind CGNAT, are checks on your connection, not on the domain record.
