Which is faster 8.8.8.8 or 8.8.4.4

That is not recommended and may even be a violation of your security policies, depending on the level of security required in your organization or by any governing agency.

DNS forwarders that only point to 8. You have a local DNS resolution solution much closer that will speed up requests if used instead. Additionally, if your DNS is set to 8. If you have a domain controller in your environment with its primary or secondary DNS pointing to an external address like 8.

Doing this should resolve external DNS resolution. Close Search. Google have the capacity to make sure that both servers are running with good request times. In fact you would probably find that all that has happened as a result of 8. A final consideration, since many more people probably use 8. So actually you might find that in some cases the secondary could be in the region of ms slower. No, not based on my experience and testing.

I assume google has a pretty good load balance infrastructure in front of the actual DNS servers and you are just hitting those - at the end both IPs might be answered by the same server. You can verify yourself using tools such as DNS tools. Since we're talking about Google here for a client-side implementation of their DNS and even as a resolver for a server, we can be certain the Google has properly distributed their DNS and has all of these optimally optimized!

Google has Servers all around the world. About anaycast here. Since Google's servers are globally distributed, there is a high chance of one being close to you. Sign up to join this community.

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.

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.

Unfortunately, Comodo stats weren't that impressive, and in our tests, we got an average query time of around 72ms. 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.
