What are DNS Servers?

DNS servers, short for Domain Name System servers, are public servers that provide a protocol that connects domain names to IP addresses so that web browsers and users are able to navigate to a website using a domain name instead of an IP address. Different free and public DNS servers offer varying degrees of speed and performance. Switching from an ISP's default DNS server to a public DNS server can provide enhanced page load speed and security.

    Google Public DNS
    The Domain Name System (DNS) protocol is an important part of the web's infrastructure, serving as the Internet's phone book, every time you visit a website, your computer performs a DNS lookup. Complex pages often require multiple DNS lookups before they start loading, so your computer may be performing hundreds of lookups a day. Configure your network settings to use the IP addresses 8.8.8.8 and 8.8.4.4 as your DNS servers. If you decide to try Google Public DNS, your client programs will perform all DNS lookups using Google Public DNS. Public DNS is only a name resolver. If you are looking for a high-volume, programmable, authoritative name server using Google's infrastructure, try Google's Cloud DNS. In addition to traditional DNS over UDP or TCP, we also provide DNS over TLS (DoT) and DNS over HTTPS (DoH) for greater security and privacy. Speed up your browsing experience.
