WHOIS Lookup

Look up domain registration details: registrar, creation and expiry dates, nameservers, status codes, and abuse contacts. Check availability, copy or download the report.

Domain registration lookup

Look up any domain

Enter a domain such as example.com. You can also paste a full URL, the address is extracted automatically.

Try:

Nothing you enter is stored. Share links keep the domain in the URL.

Your report will appear here.

Look up any domain to see its registrar, dates, DNS records, hosting, and status codes.

WHOIS is the system that records who registered a domain name and when. Every time a domain is created, the registrar stores the registration date, the expiry date, the nameservers, and a set of status codes, and this WHOIS lookup tool reads that record through RDAP, the modern registration-data protocol that replaced the old port-43 WHOIS service. Enter any domain name to see its registrar, its full date history, its nameservers, and what each status code means in plain language.

How to use the WHOIS lookup

Type a domain such as example.com into the input field and press Look up. You can also paste a full address such as https://example.com/about?x=1, and the tool extracts the domain automatically. Internationalized names work too: pasting münchen.de converts it to its punycode form before the query. Three example chips (example.com, wordpress.org, cloudflare.com) fill the field with one click, recent lookups are kept in your own browser only, and adding ?domain=example.com to the page URL runs the lookup immediately, which makes results easy to share.

What the domain report contains

The report opens with a banner showing the queried domain and a badge: Registered or Appears available. A copy button next to the badge copies the domain name. Below the banner, four stat cards show the creation date, the expiry date, the domain age (full years plus remaining days), and the time left until expiry, with a lifetime bar marking how far the domain is through its current registration period. A registered domain then shows six groups.

Registration

You see the registrar name with its IANA registrar ID, the last updated date, and the DNSSEC state, all grouped below the stat cards.

Status codes

Each EPP status code from the registry is listed with a one-line explanation. Codes such as clientTransferProhibited or serverHold are locks and holds set by the registrar or the registry, and the plain-language note tells you whether the domain is simply protected, deactivated, or inside a grace period such as redemption or pending delete.

Nameservers

The full list of authoritative nameservers is shown in lowercase, which tells you where the domain points for DNS. A registered domain with no nameservers listed carries the inactive status and does not resolve.

Contacts

Owner contact details are redacted by almost every registry for privacy, so the tool does not pretend to reveal them. Instead it shows the official abuse contact email and phone from the RDAP record, which is the correct channel for reporting spam or phishing from the domain. The name of the RDAP server that answered is shown as well, and a collapsible section holds the complete raw RDAP record for developers.

DNS records

Below the registration data, the tool resolves the live DNS records of the domain: A, AAAA, MX, TXT, and NS. This shows where the domain actually points right now, which mail servers accept its mail, and which authorization records (such as SPF entries in TXT) its owner published. Record types with no answer are left out rather than shown empty.

Hosting and IP

Each resolved web address is then enriched with hosting data: the ISP, the organization, the ASN, the registered country and city, and the reverse hostname where one exists. For example.com this identifies Cloudflare addresses (AS13335, San Francisco) behind the domain. Locations reflect the network registration, not a street address. These extra lookups run after the registration report appears, so a slow DNS answer never delays the main result.

Available domains

When no registration record exists, the tool says the domain appears available rather than claiming it is free: unregistered names can still be reserved, premium-priced, or blocked by the registry. The summary and report download still work in this state, so you can keep a record of the check.

Result actions

Five buttons sit below every report. Copy summary places a plain-text report on the clipboard, Copy JSON copies the raw RDAP record, Download JSON saves it as whois-example-com-rdap.json, Download report saves the readable version as whois-example-com-report.txt, and Copy link copies the page URL with the domain included, so the same lookup opens for anyone who follows it.

Examples

Looking up example.com returns a Registered badge with creation date Aug 14, 1995, expiry Aug 13, 2027, the nameservers elliott.ns.cloudflare.com and hera.ns.cloudflare.com, and the status codes client delete prohibited, client transfer prohibited, and client update prohibited, each explained as a registrar lock. Looking up wordpress.org returns its own registrar, dates, and nameserver set in the same layout. Entering a random unregistered name such as qrztxmpl-48291.com shows the Appears available state with no date or nameserver groups. Typing an IP address such as 8.8.8.8 is rejected with a message that points to the IP Address Info tool, which covers IP reports.

Limits

The tool queries public RDAP servers, so a domain whose registry offers no public RDAP endpoint cannot be resolved, and very new registrations can take time to appear in registry data. Availability results are a snapshot: register interest through a registrar before treating a name as yours. Nothing you enter is uploaded or stored; queries go directly from your browser to the public RDAP, DNS, and IP data services, recent lookups stay in your browser storage, and share links keep the domain in the URL.
