  That's a tricky comparison because using IPv6 required updates to the client, server, and every box in between whereas HTTP/2 only requires the endpoints to be updated and has a graceful degradation path in most cases. Unsurprisingly, it's already far more common than IPv6 because you don't have to go to every enterprise on the planet and tell them to fix things even their network team is afraid to touch. In contrast, HTTP/2 rapidly hit much higher numbers thanks to Firefox and Chrome shipping support via automatic updates. When CloudFlare deprecated SPDY about a year ago they were already seeing adoption numbers just under 70%: https://blog.cloudflare.com/deprecating-spdy/ https://blog.cloudflare.com/deprecating-spdy/
