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 you do not enable IPv6 for the specified backend subnet when you create a dedicated load balancer, the load balancer cannot use IPv6 addresses to route requests.
- If you need IPv6 networks, you must select a backend subnet with IPv6 enabled for your dedicated load balancer.
