[arin-ppml] V6 address allocation policy

> "To qualify as separate sites, locations must either be in separate
cities and/or metropolitan areas, or if within the same city or
metropolitan area, each location must have an independent connection to
the Internet, each from a different provider."

I don't believe in redefining the English language. A site, is what the
dictionary says, regardless of how it is connected to the Internet. 

It is common for companies with several sites to have them all connected
to the Internet via a gateway at a central site. Nevertheless, it would
be ridiculous for ARIN to treat this a single site.

The number one most important element of a site, in IPv6 networking
terms, is that it justifies using a separate /48 prefix. Then if the
ownership of the site changes, the new owner can keep the network
topology intact and only change the /48 prefix for one of their own.

The reason a site is not called a building or an address is that a site
could be a single floor in an office building, or one office above the
dry cleaners, or a single apartment, or it could even be floors 17
through 26 of a skyscraper, where
those floors are all housing the same insurance company.

The definition of a site is purposely a bit vague and we should not
tamper with it. In particular, since there is no need to be precise
about allocation sizes, there is no need to be precise about the site
definition.
