🌐 Comprehensive Global Domain & Aftermarket Intelligence

Dompus (domainsearch.online) is an advanced domain research engine indexing more than 340 million active, expired, and historical domain names across 1,500+ top-level extensions (TLDs). Sourced systematically from authoritative registry zone files and verified aftermarket auctions, Dompus provides researchers, security professionals, and domain investors with instant visibility into worldwide namespace trends.

Whether you need to monitor brand names across global registries, analyze historical domain sales comparables, or discover expired domains with high search authority, our sub-15ms search infrastructure delivers comprehensive intelligence directly to your browser.

📈

Domain Investors

Research aftermarket historical sales, evaluate price comparables, discover unregistered gem variations, and track daily dropped domains for backordering.

🛡️

Brand Protection

Identify typo-squatting, detect brand impersonation across new gTLDs and ccTLDs, and monitor trademark infringements before reputational damage occurs.

🔍

Threat Intelligence

Investigate newly observed domains (NOD), track suspicious naming patterns, inspect DNS records, and uncover malicious infrastructure clusters in real time.

💡

Web Creators

Brainstorm startup and project names with instant substring verification, cross-checking availability across hundreds of extensions in a single keystroke.

⚡ 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.

How do I report a data discrepancy or request API access?
