    Humorously, I violated this rule *just yesterday*. I'm helping a
    friend who has three domain names start running her own name server
    on a Mac. Even though her Mac is multi-homed, it turns out the DNS
    software doesn't work right on anything other than the "primary"
    address. For neatness sake, I wanted her to have "ns.name.com" for
    each of the three names, all on the same IP address (the primary
    address of her Mac).

    So, yes, there are real-world reasons to want multiple names on the
    same IP address, each as a legitimate name server. As Patrik points
    out, this is perfectly legal in the DNS, and should be allowed in the
    registry.

    (BTW, if you don't allow this, you should tell your registrars about
    it. NSI Registrar, that bastion of good housekeeping, accepted the
    registration changes no problem. They haven't appeared in the
    database yet, but I got the accpetances and have not heard any
    different from them yet.)
