Does ELB Support IPv6 Networks?

Dedicated load balancer load balancers support both IPv4 and IPv6 networks.

At Layer 4, when a client communicates with a dedicated load balancer using an IPv6 address, the load balancer must communicate with backend servers using an IPv6 address. At Layer 7, when a client communicates with a dedicated load balancer using an IPv6 address, the load balancer must communicate with backend servers using an IPv4 address.
