Check WHOIS data for multiple domains at once. Paste up to 20 domains and get registration details, expiry dates, and nameservers in bulk.

Bulk WHOIS lookup lets you check WHOIS registration data for multiple domains in a single query. Instead of looking up domains one at a time, you can paste an entire list and get structured results for all of them at once.
I built this tool for scenarios where checking domains individually is too slow. Whether you are managing a domain portfolio, doing due diligence on a batch of domains, analyzing competitor properties, or planning a domain migration, bulk lookup saves significant time.
Check registration status, expiry dates, and registrar for all your domains at once. Identify domains that need renewal or are about to expire.
Before acquiring domains, verify their registration history, age, and current status in bulk. Older domains with clean histories are generally more valuable.
Look up WHOIS data for competitor domains to understand their infrastructure, registrar choices, and domain age patterns.
When migrating domains between registrars or DNS providers, check the current state of all domains to identify any transfer locks or pending operations.
For single domain lookups, use the WHOIS Lookup tool which provides a more detailed view including raw RDAP data. Check domain registration timelines with the Domain Age Checker, or monitor upcoming expirations with the Domain Expiry Checker. To find domains by registrar or nameserver provider, try the Reverse WHOIS search.
