When it comes to accessing the internet, one of the most important elements is the Domain Name System (DNS). The DNS is responsible for translating human-readable domain names into IP addresses that computers can understand. Each internet service provider (ISP) typically has its own DNS server, and AT&T is no exception.
What Is a DNS Server?
A DNS server, short for Domain Name System server, is a computer server that contains a database of IP addresses and their corresponding domain names. When you type a web address into your browser, your computer sends a request to the DNS server to obtain the IP address associated with that domain name. This allows your computer to connect to the correct website.
Why Use AT&T’s DNS Server?
AT&T offers its own DNS servers for its customers to use. While you can use other public DNS servers like Google’s or Cloudflare’s, using AT&T’s DNS servers can have some benefits:
- Faster Response Times: Using AT&T’s DNS server can result in faster response times since it is maintained by your own ISP.
- Better Compatibility: Some ISPs may have custom configurations or optimizations that work best with their own DNS servers.
- Tighter Security: Since AT&T controls its own DNS servers, they can implement security measures specific to their network.
AT&T’s Primary and Secondary DNS Servers
If you decide to use AT&T’s DNS servers, you’ll need to know the IP addresses of their primary and secondary servers. Here are the details:
- Primary Server: The primary AT&T DNS server address is 18.104.22.168
- Secondary Server: The secondary AT&T DNS server address is 68.157.1
How to Change Your DNS Server Settings
If you want to use AT&T’s DNS servers, you’ll need to configure your network settings. Here’s a step-by-step guide:
