Having dealt with bug reports due to inconsistant IPv4
address parsing I don't want to have to deal with the same
problems in IPv6. I also don't want to have to deal with
"But it works on this machine" complaints because that
machine just happens to have a liberal parser.
Users can deal pretty well with errors. They have a
lot more trouble dealing with inconsistancy.
