![]() ![]() A site was inaccessible using Google DNS but was fine with any other DNS servers, we got the owners to contact google and the site got working on Google DNS again in a few hours. This is actually very rare and can be caused by many reasons, however this happened to me once and I'll mostly shortly talk about that case. As the first two are mostly mentioned by other answers, I'll talk about the last. Most people here uses a DNS on their computers to be able to connect to the popular blocked sites.Ībout an issue that might affect everyone, there might be issues with the DNS servers, mostly slow speeds, non-%100 uptime and some sites not having proper DNS records (as a bug). In my case, changing your DNS server allows you to circumvent through the DNS blocks (there are currently 113683 blocked websites in Turkey) and connect to some* blocked websites. I'll talk about the fourth and fifth point, which dns actually very clearly helps: Censorship (and bugs in DNS Servers) and Privacy. Well, other people have pointed out the malware, speed and ping points. If the names are not in your cache then changing the DNS can make a brief improvement at the start of the connection. I've made a quick drawing of what (roughly) happens.įor existing connections and if the name is in your local cache you will see no benefit to changing your DNS. If the site loads faster with the DNS changed then it is your DNS server that is bad, not the sites speed or ping (latency). Many people may equate this slow resolution of resources as being the sites "ping" being bad, when in all actuality the sites ping is perfectly fine. This can be particularly annoying to most users as it appears to be the main site being slow when in reality it is the resolution and download of all the "extra" resources that makes the site slow. Having a fast DNS server can be good if you are browsing websites that are particularly laden with off-site resources such as social media buttons, advertising images and scripts and other resources which all need their locations resolved. You might save a fragment of a second in getting the IP address of your game or Steam server, but after that the software will always be taking the direct route to the server and the speed will be the same regardless of DNS server used. If you want to prove that DNS makes no real difference then you need to be selecting the same server each time.Īs to why DNS will make no real difference? It is because it is used in the first half-second of your connection to a server (to resolve a name to an address) and maybe if your cache times out then it will use it again. Using speedtest is not relevant for testing DNS and the tests you have run are resolving to different servers with different speeds or locations which will unfairly skew your results. ![]() I've said it in a comment above, but your tests are also not fair for the purposes of your testing. There will be no improvement to ping tests at all except for possibly the initial lookup. You might get a quicker initial name resolution, especially if your ISP has a small DNS cache and doesn't see requests for that site often, but after the first request both your server and local machine will cache the request meaning that Google or OpenDNS will be slower if there is a large distance between you and their servers. What Google or OpenDNS might provide you is a slightly faster resolution of names to IP address and possibly some level of protection from known malware domain names. Your internet connection does not go through the DNS server, nor would routing through it improve your speed as chances are you will be going through several other connections (potentially on the wrong side of the world) before heading back to where you wanted to go. DNS provides name resolution services and that is it. My results are:Īll results are similar if not worse than the default DNS, if anything OpenDNS has the lowest ping but by a small margin, if I were to repeat tests that gap would go away.ĭoes DNS providers really affect speed or security or gaming? Gaming nowadays is mostly on steam, so does it affect steam?ĭNS has no effect on ping whatsoever. I did my tests, in incognito and flushed DNS after each test, I let speedtest pick the closest DNS. My brother noticed that both providers had higher ping on steam than our default DNS provider and he read that DNS won't affect Dota 2 on steam in anyway. I saw a gamer saying that google DNS is faster for regular users and OpenDNS is better for gamers because of lower ping, and all of the bloggers recommend using a DNS service. But found out that this feature isn't free. I recently heard a security expert saying that OpenDNS is the best way for malware protection. I used to use google DNS and OpenDNS long time ago, didn't notice any improvements.
