2022 saw the tenth anniversary of World IP Launch Day, a worldwide event sponsored by the Internet Society (ISOC) to commemorate the global wide-scale IPv6 adoption. Since that launch, about 40% of sites worldwide have adopted IPv6 according to Google's IPv6 adoption tracker
. The adoption is not equally spread, with France coming in at 73%; the U.S. at 46%, Brazil at 44%, but many other areas coming in below the average.
Does this record high in IPv6 adoption signify a "tipping point" for adoption? That's hard to predict, but we do believe the outlook for IPv6 growth in 2023 is good. Part of this due to the high cost of IPv4 addresses and part of it is that ISPs have new technology that is IPv6-compatible in place which reduces some of the cost of switching over.
One implication from this trend that we predict is an increase in demand for NAT64 services
in 2023. The most popular NAT function is NAT44, which maps up to 128 private addresses to one public IPv4 address. NAT64 flips that translation, translating private IPv6 addresses to public IPv4 addresses. This provides IPv6 users with access to content and resources from IPv4 servers. IPv64 opens the entire Internet to IPv6 users and softens the transition from IPv4 to IPv6.
