Dual-stack has been my go-to for ipv6 with ipv4 coexistence, but man, the headaches are real. Some older apps just refuse to play nice with IPv6, even when the OS supports it.
One tool that saved me is Wireshark—helps pinpoint where packets are getting dropped. Also, Happy Eyeballs (yes, that’s a real thing) is great for testing fallback behavior.
Anyone else using tunneling? I’ve had mixed results with 6to4.
