It worked by filtering domain name requests before they reached your device, helping block access to <strong>malicious, fraudulent, or inappropriate websites<\/strong>.<\/p>\n<p>To understand how it worked, it helps to know what the Domain Name System (DNS) does. DNS acts like the internet\u2019s address book, translating human-friendly website names (like example.com) into IP addresses that computers use. Norton DNS inserted a layer of protection at this stage. When you tried to visit a site, the service checked the request against its database of known threats and blocked anything considered unsafe.<\/p>\n<hr \/>\n<h2>Why Norton DNS was discontinued<\/h2>\n<p>Norton officially <strong>retired Norton DNS in 2018<\/strong>. The service was replaced by more advanced solutions that offer broader protection across devices and networks.<\/p>\n<p>There were a few key reasons for this change:<\/p>\n<ul>\n<li><strong>Evolving threats:<\/strong> Cybersecurity risks became more complex, going beyond simple malicious domains to include phishing, ransomware, and file-based attacks.<\/li>\n<li><strong>Limited protection scope:<\/strong> DNS filtering alone could not provide full protection against modern threats.<\/li>\n<li><strong>Shift to integrated security:<\/strong> Norton moved toward comprehensive security products that combine multiple layers of protection, such as antivirus, firewall, and identity protection.<\/li>\n<\/ul>\n<p>After the shutdown, users were encouraged to switch to newer services like <a href=\"\/norton\/us-vpn.html\"><strong>Norton VPN<\/strong><\/a> or full security suites such as <a href=\"\/norton\/us.html\"><strong>Norton 360<\/strong><\/a>.<\/p>\n<hr \/>\n<h3>What replaced Norton DNS?<\/h3>\n<p>Today, Norton includes similar and more advanced features within its modern products. Instead of relying only on DNS filtering, current tools offer:<\/p>\n<ul>\n<li><strong>Real-time threat detection<\/strong><\/li>\n<li><strong>Phishing and scam protection<\/strong><\/li>\n<li><strong>Secure browsing tools<\/strong><\/li>\n<li><strong>VPN for encrypted connections<\/strong><\/li>\n<\/ul>\n<p>Some of these solutions still use DNS-based filtering in the background, but they combine it with other technologies for stronger overall protection.<\/p>\n<hr \/>\n<h3>Key takeaway<\/h3>\n<p><strong>Norton DNS was an early, useful tool for blocking unsafe websites at the DNS level<\/strong>, but it no longer exists. Norton discontinued it in 2018 and replaced it with more complete security solutions that better match today\u2019s online threats.<\/p>\n<p>If you\u2019re looking for similar protection now, you\u2019ll find it built into modern Norton products rather than offered as a standalone DNS service.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Norton DNS was a free internet security service created by NortonLifeLock (then part of Symantec).
