C/B? I’m ruling out A because you generally can’t just assign a public IPv6 directly to an instance in GCP. Between C and B, TCP Proxy does handle IPv6 but mostly for Layer 4 traffic and specific use cases, while global load balancers are more flexible and widely used for IPv6 external services. So C feels like the more straightforward choice, but B’s not totally off if you want TCP-level proxying specifically with IPv6 support.

IPv6 is mostly supported on global load balancers for external services, so C fits best. Internal load balancers (D) don’t really handle IPv6, and assigning IPv6 directly to instances isn’t typical here. C

This one’s kinda confusing since not all load balancers support IPv6. I picked C because global load balancers usually handle external traffic and IPv6, but curious what others got?
