What Is the First Type of DNS Server Your Computer Could Query When You Search for a Domain?

When you type a domain name into your web browser’s address bar, your computer needs to find the corresponding IP address of that domain in order to establish a connection. The Domain Name System (DNS) plays a crucial role in this process by translating human-readable domain names into machine-readable IP addresses. But which DNS server does your computer query first to obtain this information?

The Default DNS Server: Your ISP’s DNS Server

By default, when you search for a domain, your computer first queries the DNS server provided by your Internet Service Provider (ISP).

This is often referred to as the “default” DNS server.

Your ISP’s DNS server is responsible for resolving domain names on behalf of its customers. It maintains a database of cached records for frequently visited websites and can quickly provide the corresponding IP addresses when requested.

Why Does Your Computer Query the ISP’s DNS Server First?

There are several reasons why your computer queries the ISP’s DNS server as the first step:

  • Efficiency: Since your ISP’s DNS server is located within your local network, it usually offers faster response times compared to external servers.
  • Customization: Your ISP can customize its DNS server to provide additional services such as content filtering or parental controls.
  • Traffic Management: By utilizing their own DNS servers, ISPs can manage and distribute network traffic more efficiently.

Alternative Options: Public DNS Servers

If, for any reason, you prefer not to use your ISP’s DNS server or if it is experiencing issues, you have the option to configure your computer to query alternative DNS servers. Some popular public DNS servers include:

  • Google Public DNS: 8.8.8 and 8.4.4
  • OpenDNS: 208.67.222.222 and 208.220.220
  • Cloudflare DNS: 1.1.1 and 1.0.

To change your computer’s DNS server settings, you can navigate to the network settings and specify the IP addresses of the desired DNS servers.

In Conclusion

The first type of DNS server your computer queries when searching for a domain is typically your ISP’s DNS server, which offers efficiency, customization, and traffic management benefits specific to your internet service provider.

However, if you prefer alternative options or encounter any issues with your ISP’s DNS server, you can easily configure your computer to query public DNS servers such as Google Public DNS, OpenDNS, or Cloudflare DNS.
