Lightsail IPv6-only instance IPv4 connectivity

Question

Will an IPv6-only instance have NAT IPv4 connectivity for making outbound connections, or is it truly IPv6 only without even a private IPv4 address?

Accepted Answer

As per [IPv6-only instance plans in Lightsail](https://docs.aws.amazon.com/en_us/lightsail/latest/userguide/amazon-lightsail-ipv6-only-plans.html)

`With an IPv6-only instance plan, your instance receives a public IPv6 address and doesn't support public IPv4 traffic.`

Just tested. The Lightsail instance has a private IPv4 address, a IPv6 address and no public IPv4 address. It is unable to establish public IPv4 connections.
