CleanBrowsing has three free public DNS server options : a security filter, adult filter, and family filter. These are the DNS servers for the security filter, the most basic of the three that updates hourly to block malware and phishing sites:. The CleanBrowsing adult filter More features can be had at a price: CleanBrowsing Plans. You can sign up for free from their signup page.
The basic set is called the "Default" servers, which block not only ads but also malware and phishing websites:. There are also "Family protection" servers Non-filtering servers are available if you're not interested in blocking anything: One reason you might want to change the DNS servers assigned by your ISP is if you suspect there's a problem with the ones you're using now.
If you can reach the website with the IP address, but not the name, then the DNS server is likely having issues. Another reason to change DNS servers is if you're looking for better performing service. Many people complain that their ISP-maintained DNS servers are sluggish and contribute to a slower overall browsing experience.
Other common reasons to use DNS servers from a third party is to prevent logging of your web activity so that you can have a more private browsing experience, and to circumvent the blocking of certain websites. Know, however, that not all DNS servers avoid traffic logging.
If that's what you're interested in, make sure you read through the FAQs on the DNS provider's site to make sure it's going to do or not do what you're after. Finally, in case there was any confusion, free DNS servers do not give you free internet access.
You still need an ISP to connect to for access—DNS servers just translate between IP addresses and domain names so that you can access websites with a human-readable name instead of a difficult-to-remember IP address. Here are several more public DNS servers. Let us know if we're missing any major providers. Some of these providers have several DNS servers. Visit the link above and select a server that's geographically nearby for the optimal performance.
Verizon DNS servers are often listed elsewhere as 4. Actively scan device characteristics for identification.
Use precise geolocation data. Select personalised content. Create a personalised content profile. Measure ad performance. If there is a line containing domain-name-servers with IP addresses, write down the IP addresses for future reference. DNS settings are specified in the Network section of the Settings menu for the selected network connection. Every router uses a different user interface for configuring DNS server settings; we provide only the generic procedure. For more information, please consult your router documentation.
Some routers use separate fields for all eight parts of IPv6 addresses and cannot accept the :: IPv6 abbreviation syntax. For such fields enter:. Expand the 0 entries to if four hex digits are required. You can configure it with the following steps. For more information see the Android blog post announcing the feature. This requires configuring all network information manually and is only recommended for advanced users. DNS servers are typically specified under advanced Wi-Fi settings. However, as every mobile device uses a different user interface for configuring DNS server settings, we provide only the generic procedure.
For more information, please consult your mobile provider's documentation. If it resolves correctly, quit the browser, load the page again and refresh it for several times to make sure the result is not from a cached web page.
From your browser, type in a fixed IP address. If this works correctly, reload the page with a new opened browser to make sure the page is loaded from scratch.
If these tests work but step 1 fails , then there is a problem with your DNS configuration; check the steps above to make sure you have configured everything correctly.
If these tests do not work, go to the next step. Roll back the DNS changes you made and run the tests again. If the tests still do not work, then there is a problem with your network settings; contact your ISP or network administrator for assistance. If you encounter any problems after setting Google Public DNS as your resolver, please run the diagnostic procedure.
This reverts your settings to using your ISP's default servers. If you need to manually specify any addresses, use the procedures above to specify the old IP addresses.

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.
DNS servers can vary hugely in speed, particularly in areas which don't always have the best internet coverage Africa, South America, Oceania. To take an example of a single day when we tested, DNSPerf. That's potentially more than a third of a second in extra waiting time before your browser is able to access any new website. This is an extreme example, to be fair.
European or US lookups may see less than 30ms variation between most DNS services, and as your device or router will probably cache the address for reuse later, even this delay will only occur very occasionally.
Still, a sluggish DNS server can noticeably slow down your browsing in some situations, and trying an alternative — especially as the best options are all free — is generally a good idea. There's a second possible benefit in terms of uptime. DNS speed depends on many factors, including your location, the distance to your nearest server, and that server having enough power and bandwidth to handle all the queries it receives.
DNS Jumper is a portable freeware tool which tests multiple public DNS services to find out which delivers the best performance for you. The program has a lot of options, but isn't difficult to use. DNS Jumper can be useful, in particular because it's checking how servers perform from your location, but it doesn't run enough tests over a long enough period to give you a definitive answer.
This gives a very good general idea of performance, and also enables seeing how services compare on different continents, as well as assessing their uptime. The steps involved in changing your DNS service vary according to your hardware and possibly your operating system version.
Generally, you must start by finding the primary and secondary nameservers for the DNS service you'd like to use. These IP addresses are normally displayed very clearly on the service website, so, for example, Cloudflare DNS uses 1. The simplest approach for home users is to update their router to use the new addresses.
Most other devices will then pick up the new DNS settings automatically, with no further work required. To make this happen you must log in to your router the default password may be printed on its base and look for the current DNS primary and secondary nameservers.
Make a note of the current values in case of problems, then replace them with the nameservers you'd like to use. If you run into problems, check out your DNS service website for any setup guidance.
Keep in mind that you can also use the tutorials of other DNS providers, as long as you remember to replace their nameserver IPs with your preferred options. OpenDNS, for instance, has specific guidance for many different router types on its support site. If router tweaks aren't right for your situation, you may have to change the DNS configuration of each individual device.
Cloudflare has short and simple guidance here , while the OpenDNS website goes into more depth. If you're troubleshooting your internet connection, or maybe thinking of switching DNS servers, it might be useful to check which DNS servers you're using at the moment.
After that, life gets more complicated as there are several potential options. Your device could be set up to use specific DNS servers; it might ask your router to give it the best DNS servers every time it boots; or it might not know anything about DNS servers, and leave your router to handle everything. Look for your network adapter and you should see its DNS servers specified in the list.
Enter that IP address into your browser, log in to the router if necessary and your DNS servers should be listed amongst the settings. Granted, not everyone wants to pay and depending on their needs they might not need to, but paid DNS is always a better choice.
