I believe that it's mentioned in the domain-system specs, which for interchange
purposes don't care if a name is suffixed with a dot or not. Some programs that
act as user agents for the domain system use it to know whether to try appending
local suffixes or not; I don't believe that that usage is anywhere in an RFC.
One place that it's NOT is in RFC821 or RFC822; the mail address
``foo@bar.baz.'' is invalid RFC822. You can't append a dot to an RFC822 domain
without invalidating it as an RFC822 domain.
