space; they are allowed to get public space if they want it.

Except they've tipped their hand already. If they've been NAT'ing 5/8 for who knows how long, it's clear they don't need public IPv4 space for their network. However, getting public space is easier than building multiple 10/8 private islands. (or so they thought :-))

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.

And that's my entire point. Thus how they've failed to demonstrate a legitimate need for what little IPv4 space is still available.

Maybe they (tmo) should get their european arm to ask RIPE for the entire 5/8 :-) (well, the 3/4th they haven't allocated yet.)
