Find subdomains of a domain name

I often needed to find sub-domains of a domain. Simple Google search for any tool doesn’t return any good results. There are couple of command line tools which does some brute forcing. But they are painfully slow.

I found another easier way to do this using Wolfram Alpha.

  1. Visit
  2. Search for the domain you want sub-domains of. For example,
  3. Click on “Subdomains” tab in web statistics section.
    Subdomain link on WolframAlpha
  4. Wolfram Alpha will list of known sub-domains of the domain
    List of sub domain names

Of course, it might not list all the sub-domains, but this should be a good enough starting point without going to the command line. 🙂
