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...

No idea why they'd be reserved though.Domain Name: A.COM Registrar: RESERVED-INTERNET ASSIGNED NUMBERS AUTHORITY Whois Server: whois.iana.org Referral URL: http://res-dom.iana.org Name Server: No nameserver Status: serverDeleteProhibited Status: serverTransferProhibited Status: serverUpdateProhibited Updated Date: 29-dec-2010 Creation Date: 01-dec-1993 Expiration Date: 08-dec-2011Even 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
