Encrypted DNS has become a standard feature in 2026, with leading public DNS providers offering support for DNS-over-HTTPS (DoH) and DNS-over-TLS (DoT) to improve privacy and security.
The best DNS server depends on what matters most to you. Some services focus on speed, while others prioritize malware protection, ad blocking, family filtering, or stronger privacy controls.
Switching to a public DNS server takes only a few minutes and can improve browsing speed, strengthen online security, and provide better privacy than many default ISP DNS services.
The majority of users will not change their DNS server. They will use whatever their internet provider gives them. It is efficient, but it may not be the quickest, safest, or most private option out there.
DNS is an acronym for Domain Name System. Imagine that the internet is an address book. When typing a website address, your DNS will convert it into an IP address. This is done for each website they visit. The DNS provider handling these requests affects browsing speed, security, and privacy.
The difference between ISP default DNS and modern public DNS has increased immensely in 2026. Other, more desirable alternatives are now free, straightforward to set up, and created for the common user.
Major DNS providers now all support encrypted DNS. DNS over HTTPS and DNS over TLS ensure that your queries are not monitored. Both are offered by default in most browsers and devices.
There's also been an increase in security. Some providers, such as Quad9 and Control D, prevent the loading of harmful sites. The tighter privacy regulations have also compelled providers to adopt policies that explicitly state they do not log information. No sharing of your data.
Cloudflare DNS is generally considered to be among the quickest public DNS services on the planet. It is compatible with DNS-over-HTTPS (DoH) and DNS-over-TLS (DoT), and it has a pretty good reputation for privacy. It's still one of the best general DNS in 2026 for those seeking a balance of speed, security, and privacy.
