Do Think Somebody Will Buy aaaaaaaaaaaaaaaaaaaa….(63 a).com?
If you say Yes, Bingo! from a.com till aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.com (63 a) are already taken by somebody.
The maximum length of a domain name is 63, that’s why it stops at 63 a.
With this kind of crazy domains buying rate, pretty soon there won’t be enough .com domains available.
