Does Google Have Its Own DNS Server?


Scott Campbell

Google does indeed have its own DNS server, known as Google Public DNS. DNS stands for Domain Name System, and it serves as a crucial component of the internet infrastructure. Its primary function is to translate human-readable domain names, like, into machine-readable IP addresses.

What is Google Public DNS?
Google Public DNS is a free Domain Name System resolution service offered by Google. It was launched in 2009 with the aim of providing users with a faster and more secure browsing experience. By using Google’s DNS servers, users can potentially speed up their internet connection and improve their overall online security.

How Does Google Public DNS Work?
When you type a domain name into your web browser, your device needs to resolve that domain name into an IP address to establish a connection with the server hosting the website. Typically, your ISP (Internet Service Provider) provides DNS resolution services for you.

However, by changing your device’s DNS settings to use Google Public DNS servers (8.8.8 and 8.4.4), you can bypass your ISP’s default DNS servers and use Google’s infrastructure instead.

Benefits of Using Google Public DNS
There are several benefits to using Google Public DNS:

1. Faster Browsing: Google has a vast network of servers distributed worldwide, which helps improve query response times for domain name resolution.

2. Improved Security: Google Public DNS automatically blocks access to known malicious websites, helping protect users from phishing scams and malware infections.

3. Bypassing Restrictions: In some cases, ISPs may block certain websites or restrict access based on location or government regulations. By using Google Public DNS, users may be able to bypass such restrictions.

4. DNSSEC Support: Domain Name System Security Extensions (DNSSEC) is a technology that adds an extra layer of security to the DNS resolution process. Google Public DNS supports DNSSEC, providing enhanced protection against DNS hijacking and spoofing attacks.

How to Configure Google Public DNS
Configuring your device to use Google Public DNS is a straightforward process. Here’s how you can do it:

1. Windows:
– Go to the Control Panel. – Click on “Network and Internet” and then “Network and Sharing Center.” – Select your active network connection.

– Click on “Properties” and then double-click on “Internet Protocol Version 4 (TCP/IPv4).” – Choose the option to “Use the following DNS server addresses” and enter 8.8 for Preferred DNS server and 8.4 for Alternate DNS server. – Click “OK” to save the changes.

2. macOS:
– Open System Preferences. – Click on “Network.” – Select your active network connection from the left pane.

– Click on the “Advanced” button. – Go to the “DNS” tab. – Click on the “+” button at the bottom left to add new DNS servers. – Enter 8.4 as the DNS server addresses.

3. Router:
The steps for configuring Google Public DNS on your router may vary depending on your router model and firmware version. Generally, you can access your router’s settings by typing its IP address into a web browser, logging in, and finding the appropriate settings section for configuring DNS servers.

Google Public DNS provides users with an alternative option for domain name resolution, offering potential benefits such as faster browsing, improved security, and the ability to bypass certain restrictions. By configuring your device or router to use Google’s DNS servers, you can take advantage of these benefits and enhance your overall internet experience.
