Most consumer devices today use some variant of the "Happy Eyeballs" protocol that prioritizes v6 to one extent or another, but "races" them (if IPv4 is faster to ping for a given DNS host it switches to IPv4 for that DNS host; otherwise it prefers IPv6). Things like NAT and CGNAT naturally slow down IPv4 so many consumer networks very heavily prioritize v6 in the "Happy Eyeballs" races. |
