Docker Hub

Docker Hub now supports  IPv6. IPv6 replaces IPv4 and solves the address space length problem. IPv6 uses 128 bits instead of 32. Docker developers said that Docker Hub, Docker Docs and Docker Scout have been completely migrated to the new protocol.

Now Docker supports simultaneous work with the old and new protocol. You can also stop using the NAT64 tool, which is used to connect IPv6 clients to IPv4 servers. You can verify that IPv6 is being used by using the tcpdump utility for network monitoring.
