Amazon EC2 service endpoints - Amazon Elastic Compute Cloud
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Amazon EC2 service endpoints

An endpoint is a URL that serves as an entry point for an Amazon web service. Amazon EC2 supports the following endpoint types:

When you make a request, you can specify the endpoint to use. If you do not specify an endpoint, the IPv4 endpoint is used by default. To use a different endpoint type, you must specify it in your request. For examples of how to do this, see Specifying endpoints. For a table of available endpoints, see Service endpoints by Region.

IPv4 endpoints

IPv4 endpoints support IPv4 traffic only. IPv4 endpoints are available for all Regions.

If you specify the general endpoint, ec2.amazonaws.com, we use the endpoint for us-east-1. To use a different Region, specify its associated endpoint. For example, if you specify ec2.us-east-2.amazonaws.com as the endpoint, we direct your request to the us-east-2 endpoint.

IPv4 endpoint names use the following naming convention:

  • service.region.amazonaws.com

For example, the IPv4 endpoint name for the eu-west-1 Region is ec2.eu-west-1.amazonaws.com.

Dual-stack (IPv4 and IPv6) endpoints

Dual-stack endpoints support both IPv4 and IPv6 traffic. When you make a request to a dual-stack endpoint, the endpoint URL resolves to an IPv6 or an IPv4 address, depending on the protocol used by your network and client.

Amazon EC2 supports only regional dual-stack endpoints, which means that you must specify the Region as part of the endpoint name. Dual-stack endpoint names use the following naming convention:

  • ec2.region.api.aws

For example, the dual-stack endpoint name for the eu-west-1 Region is ec2.eu-west-1.api.aws.
