Fast speed is important in daily internet usage. Sometimes people experience slow speed because of the slow DNS servers. Fast DNS servers are required to solve this problem. The servers can be used on different devices. Many best public DNS servers can be used to attain faster internet speed and a better user experience.
DNS and DNS Servers
DNS refers to Domain Name System. It is a system that converts the website names to an IP address number. Whenever you type any domain name, it automatically converts this into an IP address and redirects your request to the correct server for web browsing or downloading purposes. Information in DNS is stored in several distributed servers, known as DNS Servers.
When your browser wants to find the IP address for any given domain name, it automatically sends a request to these servers. The server on which this particular record is kept will answer and provide you with the appropriate information about it. Internet Service Provider (ISP) provide their users with the DNS server. It is also possible to change DNS servers provided by ISP and use public ones instead.
Public DNS Servers provide better performance and speed than ISP’s ones. They also offer some additional features and options. Public servers do not store any personal data about users. Changing your default server with these best public DNS servers can boost connection speed a lot.

Why Public DNS Servers Matter
Speeds up internet connection
Public DNS servers like Google Public DNS, OpenDNS and Level-IP are faster than ISP servers because they do not offer any filtering service by default to their users. This lowers the latency of data packets sent from the user’s device to the content server, resulting in better connectivity and performance over the web.
Offers security on public Wi-Fi networks
Most internet connections are shared among different users at various locations like airports, coffee shops or restaurants. If they are not appropriately encrypted using SSL/TLS encryption by websites to communicate between client and servers, anyone can snoop in over your data packets. Public DNS servers offer secure protocols to protect your data packets from cybercriminals to maintain privacy over the internet.
Blocks malicious domains automatically
Some public DNS servers like OpenDNS and Comodo offer advanced functions over their free versions to protect users’ devices from malware, phishing, or any other type of cyber attack launched through the internet by blocking access to those domains in real-time.
All the records are updated every week
Public DNS servers like Google Public DNS, OpenDNS and Level-IP all contain the latest data of domain names or IP addresses in their system, updated weekly to provide users with up-to-date information over their devices connected to the internet.
Secure with two encryption layers
Public DNS servers like Google Public DNS, OpenDNS and Level-IP use secure protocols like DNS-over-HTTPS and DNS over TLS to protect users against man-in-the-middle attacks launched through an internet connection by any cybercriminal or hacker.
