Bulk WHOIS Lookup
Look up registration status for a whole list of domains at once — registered, available, registrar and expiry, side by side.
How to use this tool
Paste your list
Drop a list of domains into the box — one per line, or separated by spaces or commas.
Look them all up
ns6 runs a live WHOIS/RDAP query for each domain in parallel, so a long list comes back in seconds.
Scan the results
Each domain is marked registered, available or errored, with its registrar and expiry date where it exists.
Grab the free ones
Click any available name to jump to search and register it, with free WHOIS privacy and DNS included.
Checking domains one at a time is slow when you’re researching a portfolio, clearing a brand across several names, or watching a batch of registrations expire. A bulk WHOIS lookup takes a whole list at once and tells you, for each name, whether it’s registered or available and — where it exists — the registrar and expiry date.
ns6 runs the queries live over RDAP, the modern WHOIS protocol, and in parallel, so a long list returns in seconds. Available names link straight to search so you can register the ones you want, each with free WHOIS privacy and DNS.
