Public DNS servers

Public DNS servers are available globally and allow anyone to connect to them and resolve DNS queries. The most popular public DNS servers are Google Public DNS and OpenDNS.

What is DNS?

DNS, or the Domain Name System, is the technology that allows us to type in website names (like lifehacker.com) instead of numbers (like 96.126.104.177). That number is the IP address of the server hosting Lifehacker; DNS acts like an internet-wide phonebook that links numbers to name so you don’t have to memorize them.

How do public DNS servers work?

Public DNS servers are a critical part of the Internet. They are responsible for translating human-readable domain names (like www.example.com) into the IP addresses that machines use to communicate with each other (like 192.168.1.1).

There are many different public DNS servers available, and most of them are available globally. The two most popular public DNS servers are Google Public DNS and Cloudflare DNS.

Google Public DNS was launched in 2009 and is now used by billions of devices around the world. Google Public DNS uses the Anycast network protocol, which means that it is available globally through multiple servers.

Cloudflare DNS was launched in 2018 and is quickly gaining popularity due to its privacy-focused features. Like Google Public DNS, Cloudflare DNS uses Anycast to make its service available globally through multiple servers.

The benefits of using public DNS servers

Public DNS servers are DNS servers that are available to anyone on the Internet. They are usually provided by internet service providers (ISPs) or by organizations that offer public services such as Google and Level 3 Communications.

Using a public DNS server has a number of benefits over using the DNS server provided by your ISP, including:
-Faster resolutions: Public DNS servers are usually on high-speed networks and have the capacity to resolve large numbers of queries quickly. This can result in faster browsing speeds.
-Increased security: Some public DNS servers filter out malicious websites that could steal your personal information or infect your computer with malware.
-Better uptime: Public DNS servers are typically more reliable than the DNS servers provided by ISPs, which means you’re less likely to experience downtime when using them.

If you’re looking for a public DNS server to use, we recommend trying Google Public DNS or Level 3 Communications.

The disadvantages of using public DNS servers

There are a few disadvantages to using public DNS servers. One is that they can be slow. Another is that they may not have all the features that you’re looking for, such as security or privacy features. And finally, they may not be available in all areas of the world.

Which public DNS servers are available globally?

Most public DNS servers are available globally. That said, some providers do limit access to certain servers based on geographic location. For example, Cloudflare operates anycast DNS servers in more than 200 cities around the world. However, you can only access these servers if you’re physically located within one of those cities.

How to choose a public DNS server

When you type a website name into your browser, your computer contacts a Domain Name System (DNS) server to request the IP address for that website. DNS servers are provided by your internet service provider (ISP), but you can also use public DNS servers.

There are many public DNS servers available, but not all of them are available globally. If you want to use a public DNS server that is available globally, you can use one of the following:

– Google Public DNS: 8.8.8.8 and 8.8.4.4
– Cloudflare DNS: 1.1.1.1 and 1.0.0.1
– Quad9 DNS: 9.9.9.9

How to configure a public DNS server

Most public DNS servers are available globally through anycast technology. Anycast is a networking technique that allows a single IP address to be used by multiple computers in different locations. By using anycast, public DNS servers can provide faster and more reliable service to users around the world.

There are many different public DNS servers available, but some of the most popular include Google Public DNS, Cloudflare DNS, and Quad9 DNS. To configure your computer to use a public DNS server, you’ll need to change your DNS settings. This can usually be done in your computer’s network settings or in your router’s configuration.

Troubleshooting public DNS servers

Most public DNS servers are available globally through anycast. Anycast is a network addressing and routing methodology in which each destination is assigned a single shared address and the network automatically directs traffic to the optimal location, based on connection availability and latency.
