There are some very fast, commercial DNS that usually come with your ISP package. Also, there are anonymous DNS, public DNS but also free DNS servers, among other. Overall, there is a broad array of options for you to choose.

Primary, secondary DNS servers: 18.104.22.168 and 22.214.171.124
Founded in 2005 and now owned by Cisco, OpenDNS is one of the biggest names in public DNS.
The free service offers plenty of benefits: high speeds, 100% uptime, phishing sites
The free service offers plenty of benefits: high speeds, 100% uptime, phishing sites blocked by default, optional parental controls-type web filtering to block websites by content type, along with free email support if anything goes wrong.
Commercial plans enable viewing a history of your internet activity for up to the last year, and can optionally lock down your system by allowing access to specific websites only. These aren’t going to be must-have features for the average user, but if you’re interested, they can be yours for around $20 (£14.30) a year.
If you’re an old hand at swapping DNS, you can get started immediately by reconfiguring your device to use the OpenDNS nameservers.
If you’re a newbie, that’s okay too, as OpenDNS has setup instructions for PCs, Macs, mobile devices, routers and much, much more.

Primary, secondary DNS servers: 126.96.36.199 and 188.8.131.52
Best known for its top-rated content delivery network, Cloudflare has extended its range to include a new public DNS service, the catchily-named 184.108.40.206.
The product doesn’t have any of the extras you’ll often see elsewhere. There’s no anti-phishing, no ad-blocking, no content filtering or other attempts to monitor or control what you can access, and what you can’t.
Instead, Cloudflare has focused much more on the fundamentals. These start with performance, and independent testing from sites like DNSPerf shows Cloudflare is the fastest public DNS service around.
Privacy is another major highlight. Cloudflare doesn’t just promise that it won’t use your browsing data to serve ads; it commits that it will never write the querying IP address (yours) to disk. Any logs that do exist will be deleted within 24 hours. And these claims aren’t just reassuring words on a website. Cloudflare has retained KPMG to audit its practices annually and produce a public report to confirm the company is delivering on its promises.
The 220.127.116.11 website has some setup guidance, with simple tutorials covering Windows, Mac, Android, iOS, Linux and routers. These are very generic – you get one set of instructions for all versions of Windows, for instance – but there are some pluses (IPv6 as well as IPv4 details) and you should be able to figure it out.
If you have any problems, Cloudflare offers a community forum where you can ask questions or see what others are doing, a nice extra touch which we’d like to see followed by other providers.
3. Google Public DNS
Primary, secondary DNS servers: 18.104.22.168 and 22.214.171.124
Google has its fingers in most web-related pies, and DNS is no exception: it’s free Public DNS is a simple and effective replacement for your own ISP’s nameservers.
Privacy can’t quite match the ‘we don’t keep anything’ promises of Cloudflare, but it’s not bad. The service logs the full IP address information of the querying device for around 24 to 48 hours for troubleshooting and diagnostic purposes. ‘Permanent’ logs drop any personally identifiable information and reduce location details to the city level, and all but a small random sample of these are deleted after two weeks.
Google’s support site offers only very basic guidance targeted at experienced users, warning that “only users who are proficient with configuring operating system settings [should] make these changes.” If you’re unsure what you’re doing, check the tutorials from a provider such as OpenDNS, remembering to replace its nameservers with Google’s: 126.96.36.199 and 188.8.131.52.

4. Norton ConnectSafe
Primary, secondary DNS servers: 184.108.40.206 and 220.127.116.11
Norton ConnectSafe is a free DNS service which can automatically block access to fraudulent, phishing and malware-infested websites, as well as optionally filtering sites by content.
This is a familiar idea – OpenDNS and Comodo, amongst others, do much the same thing – but ConnectSafe has one important advantage. It takes its data from Norton Safe Web, a comprehensive database on more than 50 million websites in 23 languages. The service delivers probably the best web filtering performance around, and the ability to get it for free, without having to install any software, is a major safety plus.
Setting up the service requires choosing from three levels of protection.
The Security policy blocks malicious and fraudulent websites only, and uses the nameservers 18.104.22.168 and 22.214.171.124.
The Security and Pornography policy adds support for filtering sexually explicit material, and uses the nameservers 126.96.36.199 and 188.8.131.52.
The very strict Security and Pornography and Other scheme extends the filtering to block ‘sites that feature mature content, abortion, alcohol, crime, cults, drugs, gambling, hate, sexual orientation, suicide, tobacco or violence’ by using the nameservers 184.108.40.206 and 220.127.116.11.
That’s likely to lock you out of a lot of content, but it might appeal as a way to protect young children, and you don’t have to use this policy everywhere. You could lock down your kids’ tablet with this policy, for instance, but stick with the plain Security policy for your own laptop.
There are only very basic setup instructions on the ConnectSafe site, but if you run into trouble, the tutorials on competitors such as OpenDNS may point you in the right direction. Just be sure to use Norton’s nameserver IP addresses when you change your device settings.

Comodo Group is the power behind a host of excellent security products, so it’s no surprise that the company also offers its own public DNS service.
Just as you’d expect, Comodo Secure DNS has a strong focus on safety. It doesn’t just block phishing sites, but also warns if you try to visit sites with malware, spyware, even parked domains which might overload you with advertising (pop-ups, pop-unders and more).
Comodo claims its service is smarter than average, too, detecting attempts to visit parked or ‘not in use’ domains and automatically forwarding you to where you really want to go.
Performance is key, of course, and the company suggests its worldwide network of servers and smart routing technology give it an advantage. DNSPerf’s Comodo stats are less impressive, unfortunately. As we write, DNSPerf reports its average query time as around 82ms, ranking it ninth out of the ten services tested.
That said, Comodo may still be interesting if you’re looking for an extra layer of web filtering, and the support website has some short but useful instructions on setting the service up on Windows PCs, Macs, routers and Chromebooks.

Quad9 is a young DNS outfit which has been providing a fast and free DNS service since August 2016.
The company sells itself on its ability to block malicious domains by collecting intelligence from ‘a variety of public and private sources.’ It’s not clear what these sources are, but the website says Quad9 used 18+ ‘threat intelligence providers’ as of May 2018.
That’s a little too vague for us, and we’re not convinced that using a large number of threat intelligence providers will necessarily help – the quality of the intelligence is generally more important than the quantity.
There’s no arguing about Quad9’s performance, though. DNSPerf currently rates it third out of ten for average worldwide query times, lagging behind Cloudflare and OpenDNS, but effortlessly outpacing contenders like Comodo and Norton.
Drilling down into the detail reveals some variations in speed – Quad9 drops to fifth place for North American queries – but overall the service still delivers better performance than most.

Tip: Primary DNS servers are sometimes called preferred DNS servers and secondary DNS servers are sometimes called alternate DNS servers. Primary and secondary DNS servers can be “mixed and matched” to provide another layer of redundancy.
In general, DNS servers are referred to as all sorts of names, like DNS server addresses, internet DNS servers, internet servers, DNS IP addresses, etc.
