Cloud Load Balancing IPv6 frontend generally available for regional and cross-region load balancers

Frontend configuration for load balancing incoming IPv6 traffic is now generally available (GA) for the following load balancers:

• Regional external Application Load Balancer
• Regional external proxy Network Load Balancer
• Regional internal Application Load Balancer
• Regional internal proxy Network Load Balancer
• Cross-region internal Application Load Balancer
• Cross-region internal proxy Network Load Balancer

To support client IPv6 traffic, you can configure the proxy-only subnet with a stack type of either IPV4_ONLY or IPV4_IPV6 (dual-stack).
