In a dicussion with an organization owning the "foo" trademark I'd like to look for all domains containing foo in their name or at least domains starting with "foo". How could I do such a whois search?

The best search engine I know of for this kind of search is the one provided by N@me Droppers. Type your trademark in the search bar and use the pull down to select "Only Registered Domains".

To test it, I put in "superuser" (in .com only) and it found superuser.com, androidsuperuser.com, asciisuperuser.com, asksuperuser,com, beasuperuser.com, superuserfilter.com, and so on.

Old question but still relevant. So 2 main ways:

  1. From a unix command line to query the Verisign com/net records:

    whois keyword* or whois -h whois.internic.net keyword*

Depending on the default settings of your whois program (check with 'man whois').

Note the (optional) wildcard. This will return max 50 records , priority: -,0-9,a-z

  1. From a web interface to the Internic WHOIS:

Wildcard Whois web app

Verisign wildcard lookups are also provided at: whois.crsnic.net whois.verisign-grs.net (com.whois-servers.net)

This covers .com / .net / .edu only. I do not know of similar tools for any other TLDs.

Note: normal WHOIS servers do not support wildcards.

    I get an invalid query If i use a wildcard – Wolfgang Fahl Jul 12 '18 at 13:39
  • From a command line? Or the web version above? Asterisk (*) can only be at the end, no spaces. – Paul Walsh Jul 13 '18 at 14:35
  • on a command line with no spaces – Wolfgang Fahl Jul 15 '18 at 09:08
  • Actually quotes are also necessary to prevent local file matches:whois -h whois.internic.net "keyword*" – Paul Walsh Jul 16 '18 at 10:13
  • Also whois runs on port 43 which may be blocked by some providers/facilites so the web version will be needed, even for a standard whois query but there are many sites who offer that eg. https://who.is – Paul Walsh Jul 16 '18 at 10:25
  • none of these work today :-( . I ended up writing a script to find the digits of the XXXsomeword.com domain: `for i in {100..999}; do; nslookup ${i}actualword.com >/dev/null && echo "actualword$i.com"; done` – user1778602 May 08 '23 at 19:36
  • You have your digits before and after the keyword in that code but just to confirm .. the WHOIS wildcard query only works for the wildcard at the end. – Paul Walsh Jun 09 '23 at 09:14
