I don't think this is particularly consistent with what the NIC folks said
at the last NANOG. I thought they said that they turn away any request for
less than a /19 (32 class Cs) and that although they can't legally justify
this it is not hard to enforce because it is consistent with Sprint's filters.

Even though routabilty is not the NIC's problem, they have used routability
to define policy.
