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.
