Batch Whois Lookup

Webmaster Tools 54.1k uses

A free online batch Whois lookup tool that accepts multiple domains at once and lists each domain's registration status, registrar, registration and expiry dates line by line. It automatically distinguishes registered, unregistered, registry-reserved and unsupported domains, and results can be copied or exported to CSV.

You can query multiple domains at once (one per line, up to 300). Duplicates are removed automatically, and blank lines, inline spaces and the http:// prefix are ignored, e.g. https://www.yunbug.com/abc is automatically recognized as www.yunbug.com.
