This article of theirs has setup instructions for Firefox and AndroidĭNS over HTTPS and DNS over TLS (last updated Feb 15, 2023). This is possible because DoT uses port 853, while DoH uses port 443. Note that their Secure DNS server names are the same for both DoH and DoT (despite "doh" being in the name). Each service is offered three ways: by IP address, DoH or DoT. One service is unfiltered, the other blocks ads. VPN company Mullvad offers two free DNS services to the public, as well as to their customers.Customization is very useful when logging DNS requests.ĭoT Generic: | Customized:Ĭhrome browser -> Use Secure DNS with Custom: same as DoH aboveįirefox browser -> Enable DNS over HTTPS with Custom: same as DoH aboveĪndroid Private DNS Generic: | Customized: Customized refers to naming a specific device/browser within a given profile. Generic refers to all devices/browsers that share a profile ID. A NextDNS account can have one or more profile IDs. In the below, xxxxxx is the NextDNS profile ID. Unlike other DNS providers, these IP addresses seem to vary, but expect them to start with 45.90. The setup instructions will include IP v4 addresses for old insecure DNS. This generates a free temporary account good for 7 days. Setup instructions for all supported operating systems are available on their website after you click on the blue Try it now button on the home page. NextDNS can also do logging, of both allowed and blocked DNS requests. These customized profiles can have their own block/allow lists. NextDNS allows you to create customized DNS profiles for a group of your devices, for a single device or even just for a single browser on one device. You do not need an account to use NextDNS but there are advantages to creating one such as using Secure DNS and configuring block/allow lists. My personal preference is NextDNS which blocks ads and trackers.
In April 2020, Cloudflare introduced two filtering DNS services. Cloudflare offers three different DNS services.The main Quad9 service offers malware protection.To test which DNS system/servers your computer is using, see the many available tester pages on the Test Your DNS page. That said, the two secure DNS flavors use different TCP ports, so they could both be available on a single server. Typically a company offers one server for DoH and another for DoT. New Secure DNS is specified with a server name. Old insecure DNS is specified with IP addresses (normally two of them). DNS can be a great way to get ad blocking, tracker blocking and/or malware blocking without having to install software. Some options are below, the list is far from complete. There are many choices for DNS providers and the default, using DNS servers from an ISP, is the worst option.
