You should always be ready a DNS troubleshooting strategy.<\/p>\n<p>DNS problems can lead to website downtime, which translates into lost traffic and revenue. Here&#8217;s what you need to know about DNS issues and solutions.<\/p>\n<h2>What Is DNS?<\/h2>\n<p>When you go to a website, your Internet service provider looks up the DNS record to connect to that site&#8217;s IP address. If you search for <a href=\"https:\/\/generator-guide.com\">this site<\/a>, for instance, your ISP will be able to find it because everything is connected without any errors.<\/p>\n<p>While there are many DNS servers worldwide, there are only 13 root servers on which to locate a website&#8217;s IP address. These include IANA (Internet Assigned Numbers Authority) and ICANN (Internet Corporation for Assigned Names and Numbers).<\/p>\n<h2>What Are Common DNS Problems?<\/h2>\n<p>You should understand that any problems that arise are likely between you, your registrar, and <a href=\"https:\/\/www.siteuptime.com\/blog\/2017\/11\/09\/how-web-hosting-can-impact-your-page-load-times-and-what-that-means-for-your-bottom-line\/\">your host<\/a>. Identifying where the problem is makes DNS troubleshooting easier.<\/p>\n<p>In many cases, you will only receive an error that says, &#8220;DNS server is not responding.&#8221; That message isn&#8217;t much help, but it tells you that the problem may originate with you, your host, or your registrar. In other cases, it may be a problem between your device and ISP.<\/p>\n<p>Incorrect nameservers can cause traffic to not reach your site. As many sites use third-party DNS redirect services to increase load time, the problem may be caused by those third-party hosts.<\/p>\n<p>If you&#8217;re unsure where the problem is, you can use online resources to identify the error. <a href=\"https:\/\/cachecheck.opendns.com\/\">OpenDNS CacheCheck<\/a> will query your site and provide an error report using its servers around the world.<\/p>\n<h2>How to Fix DNS Problems<\/h2>\n<p>The first step in DSN troubleshooting is to run a diagnostic check to be certain that it is a DNS error. Assuming it&#8217;s not caused by your modem, router, computer, or ISP, you can look into other options.<\/p>\n<p>In most cases, you shouldn&#8217;t need to check your DNS nameservers. However, this may be a problem if you&#8217;ve recently switched to a third-party service like <a href=\"https:\/\/www.cloudflare.com\/\">CloudFlare<\/a>. If you have changed nameservers, check to ensure that you have input the info correctly.<\/p>\n<p>You may also need to check nameservers if you&#8217;ve switched registrars or hosting services.<\/p>\n<p>You can also check that your IP address is correct. This should never be a problem, but it can happen. Check with your host to find your site&#8217;s IP address and then use <a href=\"https:\/\/www.whatismyip.com\/dns-lookup\/\">DNS lookup<\/a> to see that it matches. If there&#8217;s a problem, you should contact your host.<\/p>\n<p>In some cases, there is little you can do to correct a problem. If your host&#8217;s servers are down, you can&#8217;t fix it. You may just have to wait for connected services to resume and your site to come back online.<\/p>\n<h2>Find More about DNS Troubleshooting<\/h2>\n<p>Sometimes the problem isn&#8217;t with DNS.
