ViewDNS.info review
A broad WHOIS, DNS, reverse lookup, and API toolkit with free web access.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ViewDNS.info is a browser-based domain and IP analysis service for webmasters, IT professionals, cybersecurity specialists, and organizations working on monitoring, troubleshooting, research, or automated enrichment. Its toolset includes domain and IP WHOIS lookups, registry-based WHOIS and RDAP selection, reverse WHOIS by registrant name or email, historical IP lookup, DNS records, DNS propagation, reverse IP, reverse DNS, port scanning, and related checks. It is available through the web and an API, with no AI features or open-source offering listed.
The pricing structure combines free web access with monthly API usage tiers. The published plans show a Sandbox option with 250 trial queries and access to most APIs, while Enterprise includes higher monthly queries, access to all APIs, and custom APIs. Paid monthly query options begin with 1,000 queries for $29 per month, followed by 2,500 for $49, 5,000 for $89, 10,000 for $119, 15,000 for $149, and 20,000 for $179. This gives occasional users a free browser route and provides defined capacity choices for recurring programmatic work.
Its main strength is breadth within domain and network intelligence rather than a narrow WHOIS-only focus. Users can combine WHOIS or RDAP data with DNS records, propagation checks, reverse DNS, reverse IP, historical IP information, and registry selection. API responses are available in JSON or XML, and lookup results can be exported as CSV. ViewDNS.info is a strong fit for users who need several related investigation tools in one service. Teams needing only occasional single lookups may not need the paid API tiers, while organizations requiring all APIs or custom API work should consider Enterprise.
