Please use "edu.example" where Arnt proposed "example.edu", the

If the main consideration here is that people believe that
2821bis would be improved, or reader confusion reduced, by

My consideration is that I don't know the owner of foo.com and
can't tell if he likes that addresses in his domain are used in

Another consideration are users making up what they think are

address harvesters and spiders are everywhere. It's just bad
practice to make up example addreses if there are reserved IPs,
domains, and phone numbers for such purposes.
At some point in time we'll neeed a 2606bis, the first attempt
in this direction wasn't convincing, we discussed this in 2005:
