# Route 53

> This article explores AWS Route 53, a managed DNS service that acts as a domain registrar and manages DNS records globally.

In this lesson, we explore AWS Route 53, a fully managed domain name service (DNS) provided by AWS.

## What Is Route 53?

AWS Route 53 is a robust and scalable DNS service that facilitates several critical functions:

* It acts as a domain registrar, allowing you to purchase domain names much like popular services such as GoDaddy and Namecheap. For example, you can register a domain like KodeKloud.com directly through Route 53.
* It manages all DNS records for your domains, so once you register a domain, you can easily configure its DNS settings within Route 53.
* Being a global service, Route 53 is not limited to a single region, ensuring worldwide accessibility.

## Hosted Zones

A fundamental concept in Route 53 is the hosted zone. A hosted zone is a container for all the DNS records associated with a specific domain (e.g., KodeKloud.com). When you create a hosted zone:

* AWS reserves four dedicated name servers for that domain.
* For any additional domain, such as fastcars.com, AWS allocates another distinct set of four name servers to manage its DNS records and rules.

  * AWS Route 53 functions as both a DNS service and a domain registrar.
  * It delivers global coverage and is not confined to any specific region.
  * Hosted zones provide a structured environment where each domain receives four dedicated name servers for optimal DNS management.

## Summary

* AWS Route 53 is a fully managed DNS service and domain registrar.
* It operates at a global level.
* Hosted zones are collections of DNS records for specific domains, with each hosted zone having four dedicated name servers reserved by AWS.

In the next section, we will provide a demonstration to illustrate how to set up and manage hosted zones effectively.
