# Amazon EC2 service endpoints
<a name="ec2-endpoints"></a>

An endpoint is a URL that serves as an entry point for an AWS web service. Amazon EC2 supports the following endpoint types:
+ [IPv4 endpoints](#ipv4)
+ [Dual-stack endpoints](#ipv6) (support both IPv4 and IPv6)
+ [ FIPS endpoints](https://docs.aws.amazon.com/general/latest/gr/rande.html#FIPS-endpoints)

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](#examples). For a table of available endpoints, see [Service endpoints by Region](#service-endpoints).

## IPv4 endpoints
<a name="ipv4"></a>

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
<a name="ipv6"></a>

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`.

## Service endpoints by Region
<a name="service-endpoints"></a>

The following are the service endpoints for Amazon EC2. For more information about Regions, see [Regions and Availability Zones](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-regions-availability-zones.html) in the *Amazon EC2 User Guide*.
