Free Public DNS Servers

DNS, or Domain Name System, plays a crucial role in the functioning of the internet. DNS servers translate user-friendly domain names (e.g., portchecker.co) into machine-readable IP addresses (e.g., 45.33.50.110), enabling your device to connect with the server and perform tasks.

However, the default DNS server provided by your ISP can sometimes be slow, may block certain websites at the DNS level, or may not be secure enough for some users. In such cases, it's a good idea to switch to a reliable public DNS server from the list below.

Choosing a DNS server from the options listed above can improve your DNS lookup times, leading to a faster browsing experience. If your current DNS server is sluggish or problematic, or if you’re looking for extra security features, consider using a public DNS server. These servers can protect you from harmful, phishing websites and also block adult or unsuitable content for kids or family browsing.

Note: You may ping different DNS servers and pick the one with the lowest latency (a lower ping results in better performance) to keep DNS resolving times to a minimum.
