bulk WHOIS lookup.
Paste up to 100 domains, one per line. Get the registrar, expiry date and nameservers for all of them in a single table — read live from each TLD’s registry, not from a cached database.
what you get back
- Registrar — who sponsors the registration at the registry. Worth checking against who actually bills you; resellers make those two different more often than people expect.
- Expiry date — the registry’s date, which is the one that decides when a domain lapses.
- Nameservers — where DNS is being served from, which is usually the fastest way to work out who is hosting something.
a good use for this
The most valuable ten minutes most domain owners can spend is pasting in every domain they think they own and reading the result. Two things usually fall out: a domain registered somewhere they had forgotten about, and one expiring sooner than they thought.
If you want the expiry story for a single domain in more detail, the expiry checker adds days remaining and DNSSEC status. If you want to know who a domain is really registered through, the registrar lookup answers exactly that.
questions people actually ask.
How do I look up WHOIS for multiple domains at once?
Paste them above, one per line, up to 100. Each is looked up individually against its TLD's authoritative registry, in batches, and the results come back in a single table showing registrar, expiry date and nameservers side by side.
Why is there a limit at all?
Each domain is a live registry query rather than a lookup against a cached database, so the work is real. The cap keeps the tool fast and free without an account. If you need to watch a list on an ongoing basis rather than checking it once, that is what an owndle account does.
Is this WHOIS or RDAP?
RDAP. It reads the same registry records as WHOIS but returns structured data rather than free text, which is why dates and registrar names come back consistently across TLDs. RDAP formally replaced WHOIS as the registration data protocol.
Why does the registrar shown differ from the company I pay?
Many hosts and platforms resell domains through a wholesale registrar, so the registry record names the backend provider rather than the brand that bills you. That is normal and not a problem — but it means the registrar in a WHOIS record is not always where you go to renew.
Does this show registrant contact details?
Rarely, and that is expected. Since GDPR, registries and registrars redact personal contact data from public registration records by default. Registrar, dates, nameservers and status codes remain public; the registrant's name and email usually do not.
// stop checking one at a time
checking a list once is fine. it's not a system.
Owndle runs this lookup across your whole portfolio on a schedule, adds what each domain costs to renew against the cheapest alternative, and alerts you before every expiry. Free for ten domains, and it keeps watching after you close the tab.
