<a name="ec2-instance-naming"></a>

Understanding EC2 instance hostnames and domains is important for effectively managing and accessing your Amazon EC2 instances. Each EC2 instance can have different types of hostnames - private and public - that serve different purposes and follow specific naming conventions.

This topic explains the structure of EC2 instance hostnames, how they're constructed, and the different hostname types available. You'll learn how to view and modify hostname settings, understand when to use each type, and learn best practices for hostname management in your AWS environment.
