# 3rd Party Domains

* **A domain name registrar is a business that handles the reservation of domain names** as well as the assignment of IP addresses for those domain names.<br>

* **Domain names are alphanumeric aliases used to access websites**; for example, Google’s domain name is ‘google.com’ and their IP address is 192.168.1.1.

  * **Domain names make it easier to access websites without having to memorize and enter numeric IP addresses**.

* **If you purchase a domain from a  3rd party and would like to use it with Route 53:**
  * **Create a public hosted zone**.
  * Then, **update the 3rd party registrar NS records**.<br>

* **Private hosted zones:**
  * **Meant to be used for internal network queries**.
  * They are **not publicly accessible**.<br>

* **Public Hosted Zones:**
  * **Meant to be used for people requesting your website through the public internet**.<br>

* **NS records must be updated on the 3rd party registrar**.
