Amazon Neptune

Amazon Neptune now supports dual-stack mode, enabling database clusters to accept connections over IPv4, IPv6, or both protocols simultaneously. This allows organizations to adopt IPv6 while maintaining backward compatibility with existing IPv4 deployments.

Neptune dual-stack mode supports two configurations:

  • Private dual-stack mode: Provides IPv6 endpoints that remain isolated from the internet, suitable for internal applications and private graph databases.
  • Public dual-stack mode: Enables IPv6 endpoints accessible from the internet, supporting internet-facing applications and hybrid network environments.

Clients connect seamlessly using their preferred protocol with no application changes required.

Dual-stack mode is available in all AWS Regions where Amazon Neptune is supported. To get started, see the Neptune setup documentation.
