Domain Combo Bulk Lookup

Generate candidates for free, then explicitly verify availability when you are ready.

Combination rules

No slots yet — pick a number / letter / word type below, or add a literal.

Any candidate containing an excluded character is dropped — handy for ruling out confusable 0/o, 1/l.

Add at least one slot and one TLD to preview the combination count.

About domain combo bulk lookup

Domain combination search generates candidates from digit, letter, pinyin or word slots and checks their registration status. Combination count, upstream limits and response time affect duration; a result does not guarantee immediate registration availability.

Lookups use the public RDAP / WHOIS authoritative sources: available domains are highlighted green, registered ones greyed, failed lookups listed separately, all filling in as the stream runs. Configure your slots and TLDs, hit start to see the combination preview (will produce N combinations · e.g. xxx.com), then stream the lookup.

FAQ

Are the results accurate?

Available / registered status comes from the authoritative RDAP / WHOIS sources, so accuracy is high. Domain status changes in real time though — 'available' doesn't guarantee you can grab it this instant, so register a domain you like promptly.

How many can I check at once?

To protect the lookup data sources, each query has a combination cap (default ~1000). Beyond the cap it truncates; the preview shows both the total and the number actually checked.

Which slot types are supported?

Numbers (single / double / triple / quad / sequence), letters (single / double / pinyin initials / finals / syllables), words (common / noun / verb / adjective / city pinyin / province abbr.) and literals — combine any of them into the domain body.

Can I exclude certain characters?

Yes. Type the characters to drop together in the exclude field (e.g. 0o1l); any candidate containing them is filtered out — useful for avoiding confusable 0/o, 1/l.

References and result limitations

Online results reflect the queried source or probe state at that time. Record the target, time, nodes or data source, and parameters when citing them. A single result does not establish continuous availability everywhere.

These references explain protocol or format rules; they do not endorse results produced by this site.
