DomainHen review
A focused web toolkit for reverse WHOIS research and domain monitoring.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
DomainHen is a web-based domain intelligence research tool for investigating domain ownership and infrastructure. It is suited to small teams monitoring domain portfolios, researching related domains, checking infrastructure records, and tracking changes over time. Its feature set combines WHOIS lookup with registrar, dates, nameservers, and contact data; DNS queries for A, MX, NS, TXT, and CNAME records; reverse WHOIS searches for domains owned by the same registrant; bulk availability checks; monitoring; WHOIS history; query history; and PDF export.
The pricing structure is straightforward. The Free plan costs $0 per month and includes WHOIS and DNS lookup, reverse WHOIS lookup, domain monitoring, and PDF export. The free offering also supports bulk domain availability checking, with limited daily searches. The Pro plan costs $20 per month when billed monthly and adds unlimited searches, full WHOIS and DNS lookup, reverse WHOIS lookup, domain monitoring, and PDF export. Paid access also provides expanded bulk-check and monitoring limits, making it the more suitable option for recurring research or larger domain portfolios.
DomainHen fits teams that prefer a browser-based workflow covering ownership research, DNS inspection, availability checks, and monitoring in one place. Its narrow focus is useful for domain intelligence work, but the product is available on the web rather than across multiple platforms. Teams that need an API-led workflow, a broader integrations ecosystem, or a different approach to domain research should consider an alternative. Choose DomainHen for accessible reverse WHOIS research and portfolio monitoring; choose elsewhere when programmatic access or broader platform integration is central to the workflow.
