⚡ High-Speed Inverted Substring Search Technology

Standard registry WHOIS portals and registrar search boxes restrict users to prefix lookups or exact matches, which fail to reveal when your target term is embedded inside longer compound domains. Dompus operates on an inverted n-gram index powered by a custom ClickHouse columnar database:

By splitting domain names into indexed substrings and caching frequent search vectors at the edge, Dompus processes complex substring queries across 340M+ rows in under 15 milliseconds. Users can query with three distinct matching modes: Contains (finds substrings anywhere in the SLD), Exact (identifies identical SLD registrations across all TLDs), and Starts With (rapid prefix scanning).

❓ Frequently Asked Questions

What makes Dompus different from a regular WHOIS lookup?

Traditional WHOIS checks one domain name on a single extension at a time. Dompus searches across 340M+ domains simultaneously, revealing all registered extensions, active DNS status, and historical sales prices in a unified view.

How frequently is the domain index synchronized?

Our infrastructure synchronizes daily with authoritative zone files from Verisign (.com, .net), PIR (.org), and over 1,400 global registry operators accredited by ICANN to ensure fresh registration data.

Where do historical domain sales records come from?

Sales records are compiled from publicly disclosed and verified aftermarket auction transactions, including sales reported on Sedo, GoDaddy Auctions, NameJet, DropCatch, and Dynadot.

Can I search for domains using partial keywords?

Yes. Select the "Contains" search mode to find any domain containing your keyword anywhere in the name (e.g., searching "pay" uncovers domains like "autopay", "payvector", and "smartpayments").

Is Dompus completely free to use?

Yes, all basic search modes, keyword directories, and sales database lookups are free for public research, supported by unobtrusive advertisements.
