Does Amazon RDS support IPv6 addressing?

Can I use Internet Protocol version 6 (IPv6) addressing with Amazon Relational Database Service (Amazon RDS)?


IPv6 is available in all Regions, and you can add IPv6 addresses to both a virtual private cloud (VPC) and its subnets. Amazon RDS supports IPv6 with dual-stack mode. You can work with IPv6 on Amazon RDS when you create new instances or modify existing instances. When using Amazon RDS with IPv6, keep the following in mind:

  • The range of IPv6 addresses are assigned from Amazon's pool of available IPs, and can't be selected manually. Make sure that outbound rules for security groups and ACLs are configured accordingly.
  • When running on a dual-stack mode, Amazon RDS doesn't allow public accessibility over an internet gateway.
  • All the subnets of the database's subnet group must have IPv4 and IPv6 CIDRs attached to them to support dual-stack mode.
  • Don't delete subnets or CIDR disassociation at the VPC level. This can cause your RDS instance to become network incompatible if the DB subnet group stops supporting the DUAL network type.
