To understand why, you\u2019ll need to know a bit about DNS.<\/p>\n<p><span class=\"nutshell\">DNS stands for \u201cDomain Name System\u201d. DNS servers translate web addresses (like www.howtogeek.com) into their IP addresses (like 23.92.23.113) so users don\u2019t have to remember strings of numbers for every website they want to visit.<\/span>The Domain Name System (DNS) underpins the web we use every day. It works transparently in the background, converting human-readable website names into computer-readable numerical IP addresses. DNS does this by looking up that information on a system of linked DNS servers across the Internet. However, different DNS servers can behave\u00a0differently in terms of speed and security. So, let\u2019s take a look at how DNS works and what you can do to make sure it\u2019s working its best for you.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"Domain_Names_and_IP_Addresses\"><\/span>Domain Names and IP Addresses<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Domain names are the human-readable website addresses we use every day. For example, Google\u2019s domain name is google.com. If you want to visit Google, you just need to enter google.com into your web browser\u2019s address bar.<\/p>\n<p>However, your computer doesn\u2019t understand where \u201cgoogle.com\u201d is. Behind the scenes, the Internet and other networks use numerical IP addresses. One of the IP addresses used by Google.com is 172.217.0.142. If you typed this number into your web browser\u2019s address bar, you\u2019d also end up at Google\u2019s website.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-large wp-image-313586\" src=\"https:\/\/www.howtogeek.com\/wp-content\/uploads\/2017\/06\/dns_1-650x300.png?trim=1,1&amp;bg-color=000&amp;pad=1,1\" alt=\"\" width=\"650\" height=\"300\" onload=\"pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\" onerror=\"this.onerror=null;pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\"\/><\/p>\n<p>We use google.com instead of 172.217.0.142 because addresses like google.com are more meaningful and easier for us to remember. IP addresses are also known to change, but the DNS servers keep up with that new information. DNS is often explained as being like a phone book, where you look up someone\u2019s name and the book gives you their phone number. Like a phone book, DNS matches human-readable names to numbers that machines can more easily understand.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"DNS_Servers\"><\/span>DNS Servers<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>DNS servers match domain names to their associated IP addresses. When you type a domain name into your browser, your computer contacts your current DNS server and asks what IP address is associated with the domain name. Your computer then connects to the IP address and retrieves the right web page for you.<\/p>\n<p>The DNS servers you use are likely provided by your Internet service provider (ISP). If you\u2019re behind a router, your computer may be using the router itself as its DNS server, but the router is forwarding requests to your ISP\u2019s\u00a0DNS servers.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-313587\" src=\"https:\/\/www.howtogeek.com\/wp-content\/uploads\/2017\/06\/dns_2.png?trim=1,1&amp;bg-color=000&amp;pad=1,1\" alt=\"\" width=\"362\" height=\"438\" onload=\"pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\" onerror=\"this.onerror=null;pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\"\/><\/p>\n<p>Computers cache DNS responses locally, so the DNS request doesn\u2019t h<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp; Themes &amp; Apps\" target=\"_blank\" rel=\"noopener\">app<\/a>en every single time you connect to a particular domain name that you\u2019ve already visited. Once your computer has determined the IP address associated with a domain name, it will remember that for a period of time, which improves connection speed by skipping the DNS request phase.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"Security_Concerns\"><\/span>Security Concerns<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Some viruses and other malware programs can change your default DNS server to a DNS server run by a malicious organization or scammer. This malicious DNS server can then point popular websites to different IP addresses, which could be run by scammers.<\/p>\n<p>For example, when you connect to facebook.com while using your Internet service provider\u2019s legitimate DNS server, the DNS server will respond with the actual IP address of Facebook\u2019s servers.<\/p>\n<p>However, if your computer or network is pointed at a malicious DNS server set up by a scammer, the malicious DNS server could respond with a different IP address entirely. In this way, it\u2019s possible that you could see \u201cfacebook.com\u201d in your browser\u2019s address bar, but you may not actually be at the real facebook.com. Behind the scenes, the malicious DNS server has pointed you to a different IP address.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-large wp-image-313588\" src=\"https:\/\/www.howtogeek.com\/wp-content\/uploads\/2017\/06\/dns_3-650x300.png?trim=1,1&amp;bg-color=000&amp;pad=1,1\" alt=\"\" width=\"650\" height=\"300\" onload=\"pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\" onerror=\"this.onerror=null;pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\"\/><\/p>\n<p>To avoid this problem, ensure that you\u2019re running good antivirus and anti-malware apps. You should also watch for certificate error messages on encrypted (HTTPS) websites. For example, if you try to connect to your bank\u2019s website and see an \u201cinvalid certificate\u201d message, this could be a sign that you\u2019re using a malicious DNS server that\u2019s pointing you to a fake website, which is only pretending to be your bank.<\/p>\n<p>Malware can also use your computer\u2019s hosts file to override your DNS server and point certain domain names (websites) at other IP addresses. For this reason,\u00a0Windows 10 prevents users from pointing facebook.com and other popular domain names to different IP addresses by default.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"Why_You_Might_Want_To_Use_Third-Party_DNS_Servers\"><\/span>Why You Might Want To Use Third-Party DNS Servers<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>As we\u2019ve established above, you\u2019re probably using your ISP\u2019s default DNS servers. However, you don\u2019t have to. Instead, you can\u00a0use DNS servers run by a third party. Two of the most popular third-party DNS servers are\u00a0<a rel=\"nofollow noopener\" target=\"_blank\" href=\"http:\/\/www.opendns.com\/\">OpenDNS<\/a>\u00a0and\u00a0<a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/developers.google.com\/speed\/public-dns\/\">Google Public DNS<\/a>.<\/p>\n<p>In some cases, these DNS servers may provide you with faster DNS resolves\u2014speeding up your connection the first time you connect to a domain name. However, the actual speed differences you see will vary depending on how far you are from the third-party DNS servers and how fast your ISP\u2019s DNS servers are. If your ISP\u2019s DNS servers are fast and you\u2019re located a long way from OpenDNS or Google DNS\u2019s servers, you may see slower DNS resolves than when using your ISP\u2019s\u00a0DNS server.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-313589\" src=\"https:\/\/www.howtogeek.com\/wp-content\/uploads\/2017\/06\/dns_4.png?trim=1,1&amp;bg-color=000&amp;pad=1,1\" alt=\"\" width=\"400\" height=\"455\" onload=\"pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\" onerror=\"this.onerror=null;pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\"\/><\/p>\n<p>OpenDNS also provides optional website filtering. For example, if you enable the filtering, accessing a pornographic website from your network could result in a \u201cBlocked\u201d page appearing instead of the pornographic website. Behind the scenes, OpenDNS has returned the IP address of a website with a \u201cBlocked\u201d message instead of the IP address of the pornographic website\u2014this takes advantage of the way DNS works to block websites.<\/p>\n<p>For information on using Google Public DNS or OpenDNS, check out how to\u00a0speed up your web browsing with Google Public DNS, easily add OpenDNS to your router, and\u00a0protect your kids online using OpenDNS.<\/p>\n<\/div>\n<p><script>\n setTimeout(function(){\n  !function(f,b,e,v,n,t,s)\n  {if(f.fbq)return;n=f.fbq=function(){n.callMethod?\n  n.callMethod.apply(n,arguments):n.queue.push(arguments)};\n  if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0';\n  n.queue=[];t=b.createElement(e);t.async=!0;\n  t.src=v;s=b.getElementsByTagName(e)[0];\n  s.parentNode.insertBefore(t,s) } (window, document,'script',\n  'https:\/\/connect.facebook.net\/en_US\/fbevents.js');\n   fbq('init', '335401813750447');\n   fbq('track', 'PageView');\n  },3000);\n<\/script><\/p>\n<blockquote><p><strong><span style=\"color: #ff6600;\">If you liked the article, do not forget to share it with your friends.
