subnet_mapping block under aws_lb is missing the ipv6_address option

[shayisrael]

Hi,

I've noticed that according to TF latest documentation here:
https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/lb#subnet_mapping

The only supported parameters inside the subnet_mapping block of aws_lb are : subet_id, allocation_id and private_ipv4_address.
However, in a network load balancer with dualstack ip_address_type - there should be also the possibility to set an ipv6 from the subnet IPv6 CIDR.

See the IPv6Address option here in AWS documentation: https://www.google.com/search?rlz=1C1GCEA_enIL876IL877&ei=qWgEYIKfLYiRsAfzxaEo&q=aws+subnet_m+mappngload+balancer+ipv6addrees&oq=aws+subnet_m+mappngload+balancer+ipv6addrees&gs_lcp=CgZwc3ktYWIQAzoECAAQR1CGFVjaSWDXSmgCcAN4AoABogmIAYdHkgEJMi0xLjYtMS43mAEAoAEBqgEHZ3dzLXdpesgBCMABAQ&sclient=psy-ab&ved=0ahUKEwjCl6CwtKPuAhWICOwKHfNiCAUQ4dUDCA0&uact=5

Can ipv6_address option also be added to the TF AWS provider please?

Thanks,
Shay
