No, you could be assigned a /128 and have it function for a single host. How=
ever, let's not start doing that as it's pretty brain-dead and the reality i=
s that hardly anyone has a single host any more.
Heather has the corollaries correct.

I'm not sure I disagree, but, I certainly don't feel strongly enough about i=
t to submit a policy proposal. I will say that you are far more likely to ge=
t this changed by submitting a policy proposal than you are by complaining t=
o NANOG about it.
