Does ELB Support IPv6 Networks?¶
When a client communicates with a dedicated network load balancer using an IPv6 address, the load balancer must communicate with backend servers using an IPv6 address. When a client communicates with an application dedicated load balancer using an IPv6 address, the load balancer must communicate with backend servers using an IPv4 address.
Note
If IPv6 is not enabled for the backend subnet you select when creating a dedicated load balancer, the load balancer cannot route IPv6 requests.
If you need IPv6 networks, you must select a backend subnet with IPv6 enabled for your dedicated load balancer.
