However, if they actually have the number of hosts claimed, that
justifies the space they're asking for.  What addresses they're using
today is irrelevant.  ARIN policy only /suggests/ that they use RFC 1918
space; they are allowed to get public space if they want it.

Agreed, but what's done is done.  What /should/ have been done is now

Presumably, they "need" to renumber out of 5/8 so that their customers
can reach sites legitimately assigned addresses in 5/8.

However, those customers seem to have gotten along okay for years
without public addresses, so why not renumber them into a second
instance of 10/8?  When I was in the consulting world, I had one
customer with eight instances of 10/8, so I know it's doable.

If they want to give every customer a public address, IPv6 provides more
than they could ever possibly use--and ~34M new IPv6 eyeballs would give
the content industry a nice kick in the pants...
