Before your device connects to a site, it asks a <strong>DNS server<\/strong> &#8220;what is the IP address of this name?&#8221;. In this article we explain how DNS works, the public DNS server addresses in use as of 2026 (with filtered and unfiltered options), how to test which DNS is fastest on your own connection, and the DNS record types.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_Does_DNS_Work\"><\/span>How Does DNS Work?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n<ol class=\"wp-block-list\"><li><strong>Local cache:<\/strong> If the browser and operating system resolved the name recently, they use the stored answer.<\/li><li><strong>Resolver:<\/strong> If it is not cached, the query goes to the DNS server set in your settings. By default this is your internet provider&#8217;s (ISP&#8217;s) server; the addresses in this article are resolvers too.<\/li><li><strong>Root and TLD servers:<\/strong> If the resolver does not know the answer, it first asks the root servers, then the servers for the extension such as <code>.tr<\/code> or <code>.com<\/code>.<\/li><li><strong>Authoritative name server:<\/strong> Finally it gets the IP address from the domain&#8217;s own name server, passes it to you and caches it for the record&#8217;s TTL.<\/li><\/ol>\n\n\n<p class=\"wp-block-paragraph\">So &#8220;DNS address&#8221; usually means the IP address of the <strong>resolver<\/strong> your device uses. A website&#8217;s DNS records, on the other hand, are kept on the domain&#8217;s name servers and decide which server the site points to.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Public_DNS_Server_Addresses_2026\"><\/span>Public DNS Server Addresses (2026)<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Provider<\/th><th>Primary DNS<\/th><th>Secondary DNS<\/th><th>IPv6<\/th><th>Feature<\/th><\/tr><\/thead><tbody><tr><td>Cloudflare<\/td><td><code>1.1.1.1<\/code><\/td><td><code>1.0.0.1<\/code><\/td><td><code>2606:4700:4700::1111<\/code><br><code>2606:4700:4700::1001<\/code><\/td><td>Unfiltered, privacy-focused<\/td><\/tr><tr><td>Google Public DNS<\/td><td><code>8.8.8.8<\/code><\/td><td><code>8.8.4.4<\/code><\/td><td><code>2001:4860:4860::8888<\/code><br><code>2001:4860:4860::8844<\/code><\/td><td>Unfiltered<\/td><\/tr><tr><td>Quad9<\/td><td><code>9.9.9.9<\/code><\/td><td><code>149.112.112.112<\/code><\/td><td><code>2620:fe::fe<\/code><br><code>2620:fe::9<\/code><\/td><td>Blocks malicious domains<\/td><\/tr><tr><td>AdGuard DNS<\/td><td><code>94.140.14.14<\/code><\/td><td><code>94.140.15.15<\/code><\/td><td><code>2a10:50c0::ad1:ff<\/code><br><code>2a10:50c0::ad2:ff<\/code><\/td><td>Blocks ads and trackers<\/td><\/tr><tr><td>OpenDNS (Cisco)<\/td><td><code>208.67.222.222<\/code><\/td><td><code>208.67.220.220<\/code><\/td><td><code>2620:119:35::35<\/code><br><code>2620:119:53::53<\/code><\/td><td>Phishing protection<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Family_and_Security_Filtered_DNS_Addresses\"><\/span>Family and Security Filtered DNS Addresses<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Service<\/th><th>Primary<\/th><th>Secondary<\/th><th>What it blocks<\/th><\/tr><\/thead><tbody><tr><td>Cloudflare for Families (security)<\/td><td><code>1.1.1.2<\/code><\/td><td><code>1.0.0.2<\/code><\/td><td>Malware<\/td><\/tr><tr><td>Cloudflare for Families (family)<\/td><td><code>1.1.1.3<\/code><\/td><td><code>1.0.0.3<\/code><\/td><td>Malware + adult content<\/td><\/tr><tr><td>AdGuard Family<\/td><td><code>94.140.14.15<\/code><\/td><td><code>94.140.15.16<\/code><\/td><td>Ads + adult content, safe search<\/td><\/tr><tr><td>OpenDNS FamilyShield<\/td><td><code>208.67.222.123<\/code><\/td><td><code>208.67.220.123<\/code><\/td><td>Adult content<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Unfiltered_Alternatives\"><\/span>Unfiltered Alternatives<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n<p class=\"wp-block-paragraph\">If you do not want any blocking, Quad9&#8217;s addresses without the security filter are <code>9.9.9.10<\/code> \/ <code>149.112.112.10<\/code>, and AdGuard&#8217;s non-filtering addresses are <code>94.140.14.140<\/code> \/ <code>94.140.14.141<\/code>.
