OpenFrequently asked questions
How does the bulk domain checker work?
Paste a list of domains and the tool queries RDAP (the modern, standardised replacement for WHOIS) for each one. It returns the registrar of record, the registration date, the expiry date, and a live countdown to expiry. You can check up to 50 domains at once and export the results as CSV.
Is it really free?
Yes. No account, no credit card, no usage cap beyond the 50-domains-per-run limit (which is there to keep RDAP servers happy). Run it as many times as you like.
Why do some domains show 'No RDAP'?
Not every TLD operates an RDAP server yet, particularly some country-code TLDs. When a TLD does not support RDAP, we cannot fetch its data, so we mark it clearly rather than guess. Most major TLDs (.com, .net, .org, .io, .ai, .app, and many more) are fully supported.
What does 'Available' mean?
It means RDAP found no registration for that exact domain, so it is likely available to register. Always confirm at a registrar before relying on it, since availability can change second to second.
Can I keep tracking these domains after I check them?
Yes. Import the list into Lemon Domains and we will track expiry and renewals automatically across every registrar, with monthly sync and alerts so you never miss a renewal again.
Checking is step one. Tracking is the product.
Import your results and never miss a renewal across any registrar.
