[arin-ppml] What is a "host"?

[Vaughn Thurman - Swift Systems Inc]

Though I showed my executive IP rust using ARP to make a point similar to
this, I agree with the well articulated response below.  We need to avoid
using words that lead to arguable definitions that in turn lead to arguable
interpretations as to the application of technology.  It's too circular.

Host, can mean a whole host of things now (excuse the pun) and it should be
abandoned, and link local should not replace it.

This is far too technically complex for something that goes into policy.
In order to figure out how this impacts a given organization you need to
get a technical person involved who can find out how many link local
addresses appear on a network segment. An ordinary person has no way
of knowing this, and could easily buy some equipment that fails this
test and therefore puts their ARIN allocations at risk.

And this does not address the main issue which is virtualization of
servers, networks, switches and routers. For instance, do virtual network
segments count?

Policy needs to be straightforward and avoid these kinds of technically
complex tests which would require ARIN to send an engineer with test
equipment to determine whether the test passes or fails.
