To configure dual-stack endpoints in AWS Global Accelerator, follow these detailed steps and considerations:
Overview of Dual-Stack Accelerators
Een dual-stack versneller in AWS Global Accelerator ondersteunt zowel IPv4- als IPv6-verkeer door een paar globale statische Anycast IP-adressen te bieden voor elk protocol. This enables clients to connect over either IP version seamlessly. To use dual-stack accelerators, all endpoints associated with the accelerator must also support dual-stack (IPv4 and IPv6)[3][4].
Supported Dual-Stack Endpoints
You can add the following as dual-stack endpoints:
- Network Load Balancers (NLBs) configured for dual-stack
- Application Load Balancers (ALBs) configured for dual-stack
- Amazon EC2 instances with a primary IPv6 address attached to their network interface
Note that Elastic IP addresses cannot be added as dual-stack endpoints[4][8].
Creating a New Dual-Stack Accelerator
1. Open the AWS Global Accelerator Console.
2. Choose Create accelerator.
3. Enter an accelerator name.
4. For Accelerator type, select Standard.
5. For IP address type, select Dual-stack to enable IPv4 and IPv6 addresses.
6. Choose Next.
7. On the Add listeners page, specify the listener configuration:
- Enter the port number (e.g., 80).
- Select the protocol (e.g., TCP).
- Choose Next.
8. On the Add endpoint groups page, select the AWS Region where your endpoints reside and proceed.
9. Selecteer op de pagina Eindpunten toevoegen het eindpunttype (bijv. Netwerk load balancer, toepassingsbelastingsbalancer of EC2-instantie) dat dual-stack is ingeschakeld.
10. Select the specific dual-stack endpoint resources to add.
11. Optionally, set endpoint weights to control traffic distribution and enable client IP address preservation if needed.
12. Choose Add endpoint and then Create accelerator to finalize.
After creation, the accelerator will have two IPv4 and two IPv6 static anycast IP addresses assigned[3][5][8][9].
Updating an Existing Accelerator to Dual-Stack
If you have an existing IPv4-only accelerator, you can update it to dual-stack only if *all* endpoints behind it are dual-stack:
1. Open the Global Accelerator console.
2. Select the accelerator and choose Edit.
3. Change the IP address type to Dual-stack.
4. Save changes.
If any EC2 instances do not have a primary IPv6 address, Global Accelerator will add one automatically during the update.
The provisioning status will show In progress until the update completes, after which IPv6 addresses become available[6][8].
Important Considerations
- All endpoints in a dual-stack accelerator must be dual-stack; mixing IPv4-only and dual-stack endpoints is not supported.
- Dual-stack EC2 instances must have a primary IPv6 elastic network interface attached.
- Elastic IP addresses cannot be used as dual-stack endpoints.
- Avoid sending direct internet traffic to endpoints behind Global Accelerator to prevent connection collisions.
- Cross-account endpoint support requires specific permissions and subnet access configurations[4][6].
Samenvatting
Het configureren van dual-stack-eindpunten in AWS Global Accelerator omvat het maken of bijwerken van een standaard versneller met het dual-stack IP-adrestype, zodat alle eindpunten dual-stack ingeschakeld zijn (NLBS, ALBS of EC2-instanties met IPv6) en deze eindpunten toevoegen aan eindpuntgroepen. Deze opstelling biedt globale statische IPv4- en IPv6 -ip -adressen voor uw applicaties, waardoor de beschikbaarheid en bereikbaarheid worden verbeterd ten opzichte van beide IP -protocollen.
