I have working IPv6 and IPv4 as confirmed by various sites on 1Gbps fibre connection. Until recently Safari passed all tests for IPv6 and IPv4. Now tests report all is working, no tunnels or NAT and fully routed IPv6 yet Safari is preferring IPv4. I checked with Edge and Chrome (rarely used apart from checking sites that are not working on Safari) and each pass all tests. It does not have any effect on performance (Speedtest app and browser both return just over 900mbps on Ethernet and WiFi 6) just keen to have IPv6 working.
This all seemed fine back in July and my records shows this first surfaced in September and around iOS15. Just checked on iPhone and iPad and they have same symptom - preferring IPv4 on Safari and defaulting to IPv6 on Edge and Chrome.
Has anyone seen this? No doubt I have missed something I will end up kicking myself for.
I have disabled private relay and other features. When it was (un)helpfully turned on for me my IP address was changed and DNS was not my own. I first noticed this when Apple supported ads started reappearing in News. As I pay for News+ I was a little annoyed. I turned off private relay and reverted to my own IP address. My DNS filtering is very strict on all ads, trackers and other nuisances and suddenly all ads vanished form News and other sites again. The logs on router were helpful and showed all ads that I was seeing were coming from Apple servers. A little annoyed - I expected that from Google or MS, not Apple to whom I pay for iCloud+ and other services!
