WHOIS / RDAP Lookup
Find domain registrar, status, nameservers, registration date, and expiry.

Where does the WHOIS data come from?
The domain you type is sent to OneClickUse's server, which forwards it to a network lookup service that queries RDAP, the registration data protocol that has replaced WHOIS for generic top-level domains. Below the results, a line names the RDAP server that answered. Type the registered domain only, such as example.com, without https://, a path or a subdomain. Some country-code extensions have no public RDAP service, so a lookup for them can fail or return fewer fields.
How do I read the dates and expiry countdown?
Registered shows when the domain was first created, and Last updated moves whenever the registration is edited, for example on renewal, transfer or a nameserver change. A Registered date only weeks old marks a new domain, which is worth knowing before you trust a site that claims a long history.
The countdown subtracts the current time on your device from the expiry date and rounds to the nearest whole day. A domain expiring at 04:00 UTC on 1 November 2026, checked at 06:30 UTC on 7 October 2026, shows 25 days left, and the card is red because anything under 30 days is flagged. Dates already past read as expired, for example expired 7 days ago.
For .com and many other generic domains, the registry renews the name automatically on its expiry date, and the registrar then has a grace period in which it can still delete it. An expiry date that has just jumped a year ahead, next to an auto renew period status, does not prove the owner paid. Confirm renewals in your registrar account.
What do the domain status flags mean?
Status flags are standard EPP codes, set either by the registrar (client flags) or by the registry (server flags). Transfer, update and delete prohibited flags are locks against unwanted changes and are normal on a healthy domain. A hold flag, client or server, keeps the domain out of DNS, so it stops resolving. Redemption period means the registration was deleted and can be restored for 30 days, and pending delete means that window has closed and the name will be released within a few days.
Nameservers show which DNS provider answers for the domain. Names ending in ns.cloudflare.com point to Cloudflare, and names containing awsdns point to Amazon Route 53. To see the records themselves, use DNS Lookup, and to inspect the site's HTTPS certificate, use SSL Certificate Checker.
