Our verdict on ViewDNS Reverse WHOIS
ViewDNS Reverse WHOIS is a web-based domain intelligence tool for finding domains associated with a registrant name, person, organization, or email address. It is aimed at webmasters, IT professionals, cybersecurity practitioners, and organizations investigating domain ownership relationships. The public lookup is available without payment, making it suitable for occasional searches through a browser. API access supports programmatic searches when domain ownership relationships need to be incorporated into a workflow.
Pricing is divided across several monthly options. The Sandbox plan provides access to most APIs and includes trial queries. The 1,000 Monthly Queries plan costs $29 per month, with its allowance shared across ViewDNS APIs. The 2,500 Monthly Queries plan costs $49 per month, while the 5,000 Monthly Queries plan costs $89 per month. The Developer plan costs $49 per month, and the Professional and Business plans cost $149 and $549 per month respectively; each provides access to all APIs. The Enterprise plan provides access to all APIs and allows custom APIs. This structure gives occasional API users a lower-cost entry point while separating query volume from broader API access.
The standout capability is relationship discovery across registrant names, email addresses, people, and companies. API results are paginated and available in JSON or XML, which fits programmatic investigations and applications that need structured output. The tool is a good choice for simple lookups and focused domain ownership research, particularly when a free web search or shared API allowance is sufficient. It is less suitable for investigations that require historical records or bulk search, or for teams needing capabilities beyond the published reverse WHOIS and API workflow.
