Domain Combo Bulk Lookup

Generate candidate domains from number / letter / word slots and stream-check registrability in bulk.

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 combo bulk lookup arranges number, letter, pinyin and word slots into every combination defined by your rules, generating many candidate domains at once and stream-checking each for registrability in real time. Instead of typing names one by one, rule-based enumeration covers hundreds to thousands of combinations in seconds to surface still-available good domains.

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.
