Norton DNS is a service that enables quicker and more reliable online browsing while still providing basic protection. It does not necessitate the use of a client. You may use Norton DNS on individual PCs or enable Norton DNS on your router to secure all of your home’s devices.
Norton was among the first free public DNS providers to give some level of security. They had three policies:
A — Security (virus, phishing sites, and scam sites): 199.85.126.10
B — Security + Pornography: 199.85.126.20
C — Security + Pornography + Other: 199.85.126.30
Users may use this to build a DNS-based firewall, blocking access to undesirable material. Symantec has been researching malware attack behavior and how it spreads. Norton Secure DNS is also said to be a member of the Anti-Phishing Working Group. An industry organization devoted to educating consumers about and eliminating Internet fraud.
Norton Safe DNS has since been launched as a free service for all non-commercial uses. All a person needs to do from the Norton DNS Server site is to take a few easy steps to convert their computer over to the Norton Connectsafe DNS system. There’s even a verification website that can tell a user whether they’ve set it up correctly.
Norton DNS, like any other DNS service. It will transform the text-based Web address into the numerical IP address and redirect the user to the desired Web site. Norton DNS, on the other hand, not only accomplishes that, but it also rapidly runs a check through Norton’s Safe Web database to ensure the site isn’t known for any issues, such as phishing or malware assaults. In addition, a person may go to safeweb.norton.com to discover if any Web URL is in the database without actually visiting it. Furthermore, if there is a red signal, Norton DNS will show extensive details on why Symantec feels the site is malicious.
Despite the fact that it performs more services than a standard DNS, many people believe that the Norton DNS runs quicker. It also has 17 hosted data centers across the world to provide quick service. Given the fact that it is free, Norton DNS is not meant to be a replacement for a comprehensive solution to antivirus, antispam, and other types of anti-intrusion-based malware. Norton DNS, on the other hand, offers an extra layer of security to fight hazardous Web sites, the current way hackers use to assault their targets.
How to Set Up Norton DNS?
To begin with Norton setup, follow the steps given below.
Steps for DNS Lookup
In most cases, DNS is concerned with translating a domain name into the proper IP address. To understand how this process works. Trace the course of a DNS lookup from a web browser to the DNS lookup process and back again. Let’s go over the steps one by one.
4 Types of DNS Servers
A DNS recursor is a server that accepts requests from client machines via programs such as web browsers. The recursor is then often in charge of making extra queries in order to satisfy the client’s DNS query.
The root nameserver is the initial stage in converting (resolving) human-readable hostnames into IP addresses. It may be compared to an index in a library that links to various book racks – generally. It acts as a reference to other more particular locations.
Think of a top-level domain server (TLD) as a specific rack of books in a library. This nameserver is the following stage in the search for a certain IP address. It hosts the last element of a hostname (the TLD server in example.com is “com”).
Think of this ultimate nameserver as a dictionary on a book rack. Where a specific name may be translated into its definition. The last stop in the nameserver query is the authoritative nameserver. If the authoritative name server has access to the requested record. It will return to the DNS Recursor that made the initial request for the IP address for the requested hostname.
