At Docker we’re all about our community, so we listened to your excitement about Docker Hub support for IPv6 on the public roadmap, and now we are pleased to be introducing beta IPv6 support for the Docker Hub Registry! This means if you’re on an IPv6 only network, you can now opt in to use the registry directly with no NAT64 gateway.
Internet Protocol version 4 (IPv4), in use since the 1980s, can no longer meet the world’s growing demands for globally unique address spaces and this pool will eventually be depleted. IPv6 was created as a replacement for IPv4 and it is anticipated that it will become the new internet protocol standard. This move not only increases access to Docker Hub, but positions Hub to continue being easily accessible as the world transitions to IPv6.
Docker will now be one of the few container registries that supports IPv6. This update enables more of our community to use the world’s most popular container registry, while making sure Docker Hub is positioned to support our users in the next stage of the internet.
