DNSlytics WHOIS review
A free web lookup tool covering domains, IP addresses and autonomous system numbers.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
DNSlytics WHOIS is a web-based lookup tool from Webdevmedia for retrieving registration data linked to domain names, IPv4 and IPv6 addresses, and autonomous system numbers. It is suited to researchers, administrators and other users who need individual WHOIS results across several identifier types. Results can include registrant, organization, email, administrative and technical contact information, along with domain registration and expiration dates. IP records can include abuse-reporting information.
Its main strength is breadth within a free web workflow. Domain WHOIS coverage extends across more than 1,000 top-level domains, while the tool also queries records for major regional internet registries. That makes it useful when an investigation moves between a domain, an IP address and the autonomous system associated with network infrastructure. WHOIS data is cached for up to 30 days, which can support repeated access to recently retrieved records without changing the tool’s focus on current lookup work.
DNSlytics WHOIS is a better fit for occasional or investigative lookups than for automated or historical research. The published product details show no API access, bulk lookup capability or historical WHOIS records, so teams needing programmatic collection, large-scale processing or change tracking should choose an alternative with those capabilities. For users who want a browser-based lookup covering multiple identifier types, contact fields, lifecycle dates and abuse information, its free access keeps the workflow straightforward.
