MXToolbox WHOIS Lookup review
A free web WHOIS lookup for practical domain-registration details.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
MXToolbox WHOIS Lookup is a free web tool for retrieving domain registration information. It is aimed at individuals and teams who need practical WHOIS basics without a paid plan. Entering a domain name can return registrant information when available, registration and expiration dates, DNS hosting information, and registrar referral links when available. The tool is also part of MXToolbox’s broader collection of network diagnostic and lookup tools, with a WHOIS command in the SuperTool interface.
Its main strength is focused visibility into core domain-registration details. The lookup can help users review who is associated with a domain, when it was registered, when it expires, and which DNS hosting information is shown. Bulk lookup is also listed among the category capabilities, extending the tool beyond a single-domain workflow. Because results depend on the registrar, the information presented can vary between domains. The web interface keeps access simple, while the SuperTool placement gives users another route to the WHOIS command.
MXToolbox WHOIS Lookup fits users who want free, browser-based domain checks and do not require a broad application ecosystem. The published product details identify web access and limited API access, so teams planning extensive programmatic workflows should assess whether that access matches their needs. It is also not positioned as an open-source tool. Choose it for basic registration research, expiration checks, DNS hosting details, and registrar links; consider an alternative when your workflow depends on deeper automation or a platform beyond the web.
