Ask HN: Sorry, we can't find "www.a.com". Why?

I have not checked all the one-letter domains, but it seems that they are not available. Do we know why?

  • There are some active single-letter domains, e.g. http://x.org

    See for details: http://en.wikipedia.org/wiki/Single-letter_second-level_doma...

  • whois says:

    No idea why they'd be reserved though.

  • Even back in the day it was hard to get a one letter one. That's why I had to settle for a two letter one: http://vm.com

  • iirc two characters was the original minimum length for a hostname.

  • Paypal has x.com
