Google Public DNS

Google Public DNS is, without a doubt, the most popular custom DNS service available today. Some of the advanced features available to users are sufficient to warrant its popularity. However, some customers may be compelled to utilize alternate DNS providers due to Google’s well-known habit of tracking practically everything.

The service was first introduced in 2009, and it has since been upgraded to comply with industry requirements. In a single day, Google DNS servers handle more than a trillion DNS requests from devices.

Security technologies such as DNS over HTTPS (DoH) and DNS over TLS (DoT), both of which are used on numerous platforms to safeguard user requests, are supported by Google Public DNS.


It also supports the IPv6 protocol, which is the successor to the IPv4 standard. Google Public DNS can provide the much-needed latency boost that your ISP lacks, allowing your website to load faster. Oh, and don’t mix that with improving your internet speed.

The public DNS resolver is primarily concerned with providing filters that allow for parental controls and the blocking of pornographic content. In other words, it aims to protect children when they browse the internet. CleanBrowsing is a modest service compared to Quad9 or Cloudflare, which explains why it takes such a targeted approach.


All common security features, such as DNSCrypt, DoH, DoT, and DNSCrypt, are supported by the free version of the DNS service. Free IP addresses for families, adults, and security filters are provided by the DNS resolver.


However, it primarily sells subscription plans for a more dedicated DNS service, which is also its major source of revenue. The Basic package costs $59.99 per year and includes 19 custom filters and blocks, as well as active monitoring.


CleanBrowsing is a separate program for Windows and macOS devices that allows users to enable DNS filters with only one click. However, it’s odd that CleanBrowsing doesn’t have a more necessary Android app.
