As someone else pointed out, there are currently about two dozen TLDs with
A or MX records at the apex. Some of them have been like that for many
years, and as best I can tell, the Internet has not thereby collapsed.
How many label our hosts with two letter domain names?
Beats me, but since there are several hundred TLDs, it seems to me that
the chances are pretty low that everyone in the world has managed to avoid
using them as host names.
Do you have any evidence that they have not caused problems?
Hey, you're the one claiming that there's a global disaster in progress of
which nobody seems to be aware. If there's evidence, tell us about it.
I suspect that other sites that used the names just put up
with the pain of renamimg hosts along with the resultant
risk of email being misdirected.
Perhaps you could start by asking people at ai.mit.edu how long their mail
has been unusable.
Look, we all know there's an unlimited number of ways one can screw up
mail and web configuration. If you put an underscore in the name of a web
server, as often as not it sort of works even though it's flatly forbidden
by RFCs. Or if you put an @ or % character in the local part of your
e-mail address, it'll fail all over the place even though the RFCs say
that's fine.
Why is this particular configuration issue so uniquely awful that the IETF
and ICANN need to tie themselves up in knots about it? ICANN has plenty
of real problems on its plate, like registrars who steal people's names
and won't give them back. This isn't one of them.
