Some interesting stats from <https://www.tomshardware.com/networking/ipv6-usage-reaches-historic-50-percent-across-google-services-matching-ipv4-increased-usage-eases-pressure-on-the-ipv4-address-market-as-new-protocol-designed-in-1998-finally-hits-its-stride>: • 50% of users of Google’s services connect over IPv6 • 43% of the world uses IPv6, with some parts approaching 50% • Cloudflare reports 40% of its traffic is done via IPv6 Choice quote: Some people still think that the additional 20 bytes or so of an IPv6 packet header translates to significant bandwidth losses, higher CPU usage, and hair loss. The reality is that even 11 years ago, Facebook's tests saw that IPv6 connectivity was around 10-15% faster overall, while networking giant Akamai noticed a 5% speedup in mobile page loading. The speedups are almost assuredly due to the fact that with IPv6, there's very little need to do math with NAT, proxies, and other shenanigans, as in most instances, everything can directly connect to everything else.
