This does not belong to NANOG. I'm only CCing so you're not
inundated with responses.
1. A host can have multiple addresses. These do not have
to be on the same network. It's a redundancy thing.
Since the host in question is a nameserver, it's even
more reasonable.
2. Reserved addresses can be used anywhere. They are just
not supposed to be leaked into the public internet.
sigh.
