You're describing IPv6. I'm describing IPv4 that uses the current dotted-quad as the network address and adds a new host address: The routing tables don't get bigger, AS numbers are 32 bit anyway and unlikely to get bigger, DPI is actually easier than with NAT since there's no ambiguity, there's no new media types, and upgrades can be done piecemeal. Seriously, it's better than IPv6 in every way but one: by being cheaper to deploy companies and consultants can't charge extra for IPv6 readiness over a few decades.

  I had a 32 bit AS number almost a decade ago. I'm still waiting for an IPv6 address.

    And hardware had problems with 32 bit ASNs even up to a year ago. Inline flow generation was broken on Juniper and Cisco stuff for a while.

      Arista just added 4 byte ASN support to BGP in EOS, in the last release in December. Just FYI.

    Well, and I've had native (non-tunneled) IPv6 for more than a decade on my DSL at home ... what's your point? Routers have been able to handle IPv6 since quite a bit before the introduction of 32 bit AS numbers, so, if you wanted to be able to speak to 32 bit BGP peers, you had to upgrade to a router that can do IPv6 as an unavoidable side effect.

I'm describing a growing network. WLAN support doesn't require new hardware because of IPv6, it requires new hardware because old 3com 3c509 cards didn't support WLAN. Increasing number of customers require increasing number of customer-facing routers and router ports because each customer requires a connection, it's nothing specific to v6. And so on.
