You could mask the sensitive part of it, but, anyway, I actually see
RAs sent from a global address.  I don't know why it behaves that way,
but it's no secret that there are broken implementations so it's not
surprising.  Since the implementation is this broken I don't see any
point in discussing this particular case here - that is, no one here
will be able to answer why a broken implementation is broken or why an
operator uses that broken implementation.  You'll just need to talk to
that operator.
