You'll find that ping supports every type of IP address format that you
can think of and a whole bunch that you can't; it turns out that the
implementation of the conversion functions in the resolver libraries are
very flexible. But we need not allow all that flexibility in the article
format; bracketted IP addresses are a very special and rare exception
anyway, and I don't see any particular reason not to reasonably limit
their syntax.
I have seen [127.1] used as a domain. I don't really care whether we
support it or not, but I think that we should limit our efforts to support
weird things at least to just zero-folding and not other bases.
