assignIpv6Addresses

Assigns the specified IPv6 addresses to the specified network interface. You can specify specific IPv6 addresses, or you can specify the number of IPv6 addresses to be automatically assigned from the subnet's IPv6 CIDR block range. You can assign as many IPv6 addresses to a network interface as you can assign private IPv4 addresses, and the limit varies by instance type.

You must specify either the IPv6 addresses or the IPv6 address count in the request.

You can optionally use Prefix Delegation on the network interface. You must specify either the IPV6 Prefix Delegation prefixes, or the IPv6 Prefix Delegation count. For information, see Assigning prefixes to network interfaces in the Amazon EC2 User Guide.
