I have seen 1000::/32 come in once and a while, but I've noticed that it's
hard to catch from where this is coming from. But I've not seen the
others.
But it does point to the larger lesson that just because it is IPv6, it
doesn't mean that prefix-fiters (and other tools) aren't required like in
IPv4.
