Bulk WHOIS Lookup

Overview

The Bulk WHOIS Lookup tool performs WHOIS lookups for multiple domains at scale. It extracts registration details including registrar information, creation dates, expiry dates, name servers, DNSSEC status, registrant organization, and calculated domain age for each domain in your list.

This tool is essential for domain investors, cybersecurity analysts, brand protection teams, and SEO professionals who need to check registration details for hundreds or thousands of domains efficiently. It replaces the manual process of looking up domains one at a time through ICANN WHOIS.
