DNS Filtering is Making Your Internet Safer, Faster, and Reliable

DNS filtering gives protection from online threats such as viruses, malware, ransomware, phishing attacks, and botnets. The Domain Name System (DNS) is the Internet's counterpart of a telephone directory. They keep up a registry of domain names translate them to Internet Protocol (IP) addresses. Since domain names are easier for individuals to recall, PCs or machines, get to websites based on IP addresses.

Despite the fact that the idea of DNS is easy to understand, many may have a few confusions about DNS filtering that could influence getting it to work securely and reliably.

DNS Filtering

DNS filtering starts with a the test that will list DNS records for a domain in priority order, in three stages:

  1. Writing a website address and set off a DNS query.
  2. The DNS server specified in the network interface configuration gets the request and looks into the IP address relating to that domain.
  3. As long as the domain name exists, the corresponding IP address is returned, and the browser at that point utilizes that IP address to communicate directly with the web server for that domain.

Once the DNS reply is received with the IP address of the domain name server, DNS is no longer associated with the communications between the browser and the server.

This procedure then gives a chance for using DNS as a very essential, quick, and low-bandwidth filter to protect users from phishing sites, botnets, and other hazardous sites. DNS filtering secures the system by only providing lookup requests with a valid IP address for safe websites, but returns a local IP address to deliver a block page for forbidden sites.

DNS logging, on the other hand, will indicate which lookups people have performed, but not which sites they really went to, nor for how long. For that level of detail, you’ll require a fast local proxy/filter to look at all of the actual web traffic.

DNS filtering is such an easy and clear alternative for web filtering. Technology isn’t the main piece of the solution to website access. An acceptable usage policy is likewise required. Furthermore, the speed and performance of DNS servers can differ. Slow or poor domain resolution will bring about slow and less solid web browsing. However, you can run speed tests on DNS servers to compare performance.

DNS filtering products enable you to screen, control, secure and protect your business from online dangers. Additionally, it’s based in the cloud and it’s easy to use. The two key elements of these DNS filtering products are web security and web content control. A user types a URL into their browser, this request is sent to the cloud servers and the request is permitted or blocked. In the event that the request is blocked, the user is presented with a block page educating them why it was blocked. If the user is permitted, they are passed on to the requested URL.

Key Advantages of DNS Filtering:

  • Block Malware & Malicious Sites - blocks access to malware, ransomware, phishing attacks, viruses, malicious sites, and spyware. It eliminates malicious content at the source.
  • Control Web Access - enables you to control internet access in your organization at a lower level and from an easy to use administration console.
  • Benefits of the Cloud - Sent as a cloud-based service, the DNS Filtering solution requires a basic DNS redirect to the servers.

The Advantages of using a DNS Filtering service

  • Enhances security by blocking access to malicious and hazardous websites
  • Keeps malware downloads from malicious or hacked sites
  • Stays up with the latest defense with targeted threat analysis and updates to secure your customers as threats emerge
  • Use policy-based controls to oversee access with profound blocking and filtering
  • Prevents users accessing material that could hinder efficiency or cause offense

There are numerous things that could be causing delays in your connection speed. Each internet service provider has their own DNS server, however, it's not generally the fastest. If your computer can't look up IP addresses rapidly, it seriously slows down your browsing. Often, the fastest DNS server is the one that is physically nearest to your area. If you switch to a faster one, that implies it looks up those IP addresses and gets you where you need to go speedier than before. It may not appear like a great deal, but when a page has to load things from a bunch of various sources, it can add up.
