Longest Single Letter .com Domain Name

I was looking for a domain name, got bored at not finding any I liked, so started looking for other, more specific domain names. I tried aaaaaa.com but this was taken, then aaaaaaa.com , then aaaaaaaa.com and so on. I was surprised by how many of these were registered.

So I began to wonder how may a’s it would take before there was a domain name that I could register. Then I expanded that to wonder about b and c …

Here, I wrote a script:

#!/bin/bash
whoischeck() {
 # FROM https://linuxconfig.org/check-domain-name-availability-with-bash-and-whois
whois $1.com | egrep -q '^No match|^NOT FOUND|^Not fo|AVAILABLE|^No Data Fou|has not been regi|No entri'
  return $?
}
lettercheck() {
 A=$1
 for ((i=1;i<=64;i++))
 do
  if whoischeck $A; then
   echo "$A.com is available"
   return
  fi
  A=$A$1
 done
}
for l in a b c d e f g h i j k l m n o p q r s t u v w x y z
do
 lettercheck $l
done

Here are the results, these are the smallest single letter .com domains you can register (as of 21/7/2020):

aaaaaaaaaaaaaaaaaaaaaaaaaaa.com
bbbbbbbbbbb.com
ccccccccccccccccccc.com
ddddddddddddddd.com
eeeeeeeeeeeeeeeeee.com
fffffffffffffffff.com
gggggggggggggg.com
hhhhhhhhhhhhhhhh.com
iiiiiiiiiiiiiiiii.com
jjjjjjjjjjjjjj.com
kkkkkkkkkkkkkkkkk.com
lllllllllllllllllllllll.com
mmmmmmmmmmmmmmmm.com
nnnnnnnnnnnnnnnn.com
oooooooooooooooooo.com
pppppppppppppp.com
qqqqqqqqqqqqqqq.com
rrrrrrrrrrrrrr.com
ssssssssssssssssss.com
ttttttttttttttttt.com
uuuuuuuuuuuuuu.com
vvvvvvvvvvvv.com
wwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww.com
x*.com are all registered
yyyyyyyyyyyyy.com
zzzzzzzzzzzzzzz.com

The fact that you can’t register a single x*.com domain name is pretty obvious why. But why does Alibaba own wwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww.com ?
