# Amazon Lightsail endpoints and quotas
<a name="lightsail"></a>

To connect programmatically to an AWS service, you use an endpoint. AWS services offer the following endpoint types in some or all of the AWS Regions that the service supports: IPv4 endpoints, dual-stack endpoints, and FIPS endpoints. Some services provide global endpoints. For more information, see [AWS service endpoints](rande.md).

Service quotas, also referred to as limits, are the maximum number of service resources or operations for your AWS account. For more information, see [AWS service quotas](aws_service_limits.md).

The following are the service endpoints and service quotas for this service.

**Note**  
Lightsail for Research is available in the same AWS Regions as the Amazon Lightsail service with the exception of the US East (N. Virginia) Region. Lightsail for Research also uses the same endpoints as Lightsail.
The Amazon Lightsail service offers dual stack endpoints so that you can send it either IPv4 or IPv6 requests. In the following table, dual stack endpoints resemble `lightsail.region.api.aws` and IPv4 endpoints resemble `lightsail.region.amazonaws.com`. For more information, see [Dual stack endpoints](https://docs.aws.amazon.com/general/latest/gr/rande.html#dual-stack-endpoints).
