Our verdict on DomainIQ
DomainIQ is a web-based domain intelligence platform for researching domain names, registrants, organizations, email addresses, IP addresses and related infrastructure. It is designed for security professionals, attorneys, law enforcement, domain investors and domain-industry professionals. Its core reverse WHOIS searches can use a domain, email address, registrant name or company name, while historical WHOIS records help connect domains with past ownership. The product also includes domain reports, reverse DNS, reverse IP, reverse MX, bulk lookup tools and monitoring.
Pricing is structured around three plans. Pro costs $49.95 per month and includes 250 basic reports per day, 250 comprehensive reports, 50 WHOIS history reports per day, reports with up to 100 results, lookups with up to 1,000 results and monitoring for up to 1,000 items. Expert costs $149.95 per month and raises those limits, including 2,500 basic reports per day, 150 WHOIS history reports per day, reports with up to 1,000 results, lookups with up to 10,000 results and monitoring for up to 5,000 items. Enterprise adds unlimited basic reports, high-volume query support, priority technical support, custom API calls and tool development, individual sub-account credentials and premium access to additional data.
DomainIQ stands out through breadth rather than a single narrow workflow. Web access covers interactive research, while the HTTP API supports XML, JSON, CSV and INI output modes for programmatic use. Monitoring spans domains, keywords, registrants, email addresses and DNS, giving teams a way to continue tracking relationships after an initial search. Custom enterprise reports, data mining and APIs extend the platform for specialized investigations. Choose DomainIQ when reverse ownership research, historical records, infrastructure lookups and monitoring belong in one workflow; occasional users seeking a simple, low-cost lookup tool should look elsewhere.
