# DNS addressing and custom domains in AWS Global Accelerator
<a name="dns-addressing-custom-domains"></a>

This chapter explains how AWS Global Accelerator does DNS routing and includes information about using a custom domain with Global Accelerator. It also includes the steps for configuring bring your own IP (BYOIP) addresses to use with accelerators in Global Accelerator.
+ **DNS addressing**: When you create an accelerator, Global Accelerator assigns a default Domain Name System (DNS) name to your accelerator.
+ **Custom domain name**: You can configure DNS to use your custom domain name (such as `www.example.com`) with your accelerator, instead of using the assigned static IP addresses or the default DNS name.
+ **BYOIP IP addresses**: You can bring your own IP addresses to AWS to add to an accelerator instead of, or together with, the static IP addresses that Global Accelerator assigns to you.
