I'm still trying to understand how you know what the locale of the
various network identifiers are.  People might recall that this was
one of the problems we have identified as a serious issue in the past.
You can know what the locale is, maybe, at lookup time, but since the
information doesn't travel around with the identifier you can't know
what the locale is at creation time.  And that, of course, is how you
get a security problem out of this.
