The reality is they just make it work with current products, over IPv4, and the IPv6 usage graph is stuck at 50% and doesn't really move up (at least not fast enough).
When measuring use, we shouldn't measure bytes moved per AFI. Because if you care about bytes moved, you can pick some big tech that loads their global caches over IPv6 and you might be confused to think that traction is good. We should be looking at SRC,DST pairs over all traffic, billion bytes is the same as 1 byte, the internet is still sometimes used for something else than looking at big tech ads, not much by byte count, but by SRC,DST count it is something. Transit shops see maybe 15% total IPv6, but this isn't 100% doing 15%, this is a couple shops doing very high %. At any rate, we are already very late, the IPv4 market exists, is non-trivial size and has already caused known and unknown damage to the economy. How many products never happened, because people didn't have CAPEX to acquire the IPv4 their idea needed and it didn't move further from internal dialogue? How many competitors didn't happen? For big tech nothing costs anything, they lay the fibers, because they can pay those with ads, unlike communication shops who cannot afford to build fiber, because margins aren't there without ads. Big tech buys IPv4 in the billions, because a billion is an atomic sum of money to them. -- ++ytti
