Re: 10.0.0

        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.
