# Access Server and DNS Configuration Guide

This page provides information about the Domain Name System (DNS) and Access Server.

## How DNS works

The Domain Name System (DNS) maps domain names to IP addresses using name resolution services. When you enter a domain name in a browser, DNS translates it to an IP address to connect you to the correct destination.

## DNS and Access Server

You can configure DNS for clients that connect to your Access Server. Access Server can have clients use the same DNS servers as the Access Server host, push specific DNS servers for clients, or not alter clients' DNS servers.

You can set these options in the Admin Web UI on the **VPN Settings** page.

You can also alter DNS resolution zones and default domain suffix settings on the **VPN Settings** page. DNS resolution zones allow you to configure a split-DNS setup, defining DNS zones that resolve to DNS servers pushed from Access Server.

An optional, Windows-OS-specific setting is the DNS domain suffix because Windows clients might only use the first domain provided in DNS resolution zones.

For more, refer to the user manual's [VPN settings page](https://openvpn.net/as-docs/configuration/#vpn-settings).
