What a WHOIS record contains

Each field and what it tells you about a domain's registration.

🏢

Registrar

The company that sold the domain registration — GoDaddy, Namecheap, Google Domains, Cloudflare, etc. Contact the registrar to transfer or update the domain.

📅

Creation Date

When the domain was first registered. Older domains are generally trusted more by email providers and search engines than newly registered ones.

⏰

Expiry Date

When the registration expires. After expiry there is usually a grace period before it becomes available to others. Monitor this to avoid accidental expiry.

🌐

Nameservers

The DNS servers authoritative for the domain — tells you who manages DNS. Changing these is how you point a domain at a different host or CDN.

👤

Registrant

The registered owner. Since GDPR (2018) this is often redacted for privacy by European registrars or when WHOIS privacy protection is enabled.

🔒

Domain Status

Codes like clientTransferProhibited (locked), pendingDelete (expiring), serverHold (suspended). Multiple status codes can be present at once.

Supported TLDs and their registries

Each TLD has its own authoritative WHOIS server — we query the right one automatically.

GDPR and WHOIS privacy

Since GDPR came into effect in 2018, most European registrars and many global ones redact personal contact information from public WHOIS records. You may see "Data Redacted" or "Withheld for Privacy" where registrant details used to appear. The registration dates, registrar, nameservers and domain status are almost always still visible. To find contact information for a registrant, use the registrar's official abuse/contact process.

Frequently asked questions

What is a WHOIS lookup?

A WHOIS lookup queries the public registry database for a domain or IP address to find registration information — who registered it, when it was created, when it expires, which registrar manages it and which nameservers handle its DNS.

Can I find out who owns a domain?

Since GDPR (2018) most registrars redact personal contact information from public WHOIS records. You can still see the registrar, registration dates and nameservers. Some registrars offer privacy protection that masks the owner's identity entirely.

How do I check if a domain is about to expire?

Run a WHOIS lookup and look at the Expiry Date field. If it's within the next 30–60 days and you own the domain, log in to your registrar and renew. Most registrars offer a redemption grace period after expiry before the domain becomes publicly available again.

Why does WHOIS return different results for different tools?

WHOIS is a decentralised system — each TLD has its own authoritative registry server. Different tools may query different servers or cache results. For the most authoritative result, query the TLD's official registry server directly.
