DNS

Every internet-connected device has its own IP address, which is used by other devices to find it. Domain names are converted to IP addresses by the domain name system (DNS), which are then used by browsers to load web pages. DNS servers allow users to type ordinary phrases into their browsers, such as example.com, without having to remember the IP address for each website.

Why use a DNS server?

A DNS server is a computer with a database containing the public IP addresses connected with the names of the websites that a user visits while using the IP address. The domain name system (DNS) serves as the internet's phone book. When people type domain names into web browser address bars, such as www.example.com, the DNS discovers the correct IP address. The device is directed to the correct location to access the site's data by the IP address of the site. The browser takes the right IP address from the DNS server and uses it to transfer data to the content delivery network (CDN) or origin servers. After that, the user will be able to access the website's information. The DNS server begins the process by determining the IP address that corresponds to a website's URL.

How does DNS work?

DNS functions similarly to a phone book, however instead of mapping people's names to street locations, it maps computer names to IP addresses. A "DNS record" is the name given to each mapping.

Because the internet has so many computers, compiling all of the records into one large book is impractical. DNS is instead divided into smaller books or domains. Because domains can be quite big, they are divided into smaller books called "zones." It would be impractical to store all of the books on a single DNS server.

Instead, there are several DNS servers that keep all of the internet's DNS records. Any computer can ask their DNS server for information about a number or a name, and their DNS server understands how to ask – or query – other DNS servers when they require a record. An "upstream" query is when a DNS server queries other DNS servers. Queries for a domain can be directed "upstream" until they reach the domain's authority, also known as the "authoritative name server."

Administrators administer server names and IP addresses for their domains on an authoritative name server. A DNS administrator modifies their authoritative DNS server (also known as a "master DNS server") if they want to add, alter, or delete a server name or IP address. There are also backup DNS servers, which keep duplicate DNS entries for their zones and domains.

Name servers (NS) connect URLs to the right IP address of the website's server. Name servers are servers that organize and route internet traffic. When users type a website address into their browser's search bar, the browser begins the process of decoding the site and redirecting traffic to the appropriate web browser. The name server is in the midst of everything, storing all of the information about which websites are hosted where. The name server converts the domain name into an IP address, connecting information that is understandable by humans with information that is understandable by computers.

What is the difference between a name server and a DNS server?

DNS is made up of name servers that connect IP addresses to domain names, saving us from having to remember long strings of digits when visiting a website. On the other hand, the name server aids in the storage and organization of those particular DNS records. DNS is working in the background during the milliseconds it takes to load a webpage. When a user enters www.example.com, the URL is divided into sections. The ".com" redirects the inquiry to a top-level domain name server, which then directs the query to the "example" name server. The information is then returned to the browser.

Why are name servers important?

In a nutshell, name servers are servers that use the Domain Name System (DNS). Domain names would be converted to machine-readable IP addresses via name servers. This procedure allows users to access websites by merely typing a domain name rather than an IP address. A name server aids in the discovery of websites. The name server sends traffic to your website when someone puts the domain name into a search engine. When the browser establishes contact with the server, it sends a request for the files the user is looking for, and the browser displays the webpage.

Network Traffic Log The volume of data traveling across a network at any given time is recorded in a network traffic log. Network traffic is the most important factor in network traffic measurement and control. The input and outflow of network packets within an organization's network are referred to as network traffic. Understanding and monitoring this data is a crucial part of securing a company's network.

Why use a network monitoring log?

The internet network is a vital component of a cyberattack. Gaining access to network data is another area where network administrators can detect and stop threats early. Here are a few more benefits of network log monitoring.

Improved insight into network-connected devices

Troubleshoot operational and security issues more easily.

With detailed detail and additional network context, you can respond to investigations faster.

What is the best way to keep track of network traffic logs?

Figure out where the traffic is coming from. Identifying and tracking the source of network traffic will aid in the detection of any irregular data flow. Domain access logs, data from connected devices, and other network applications are all important sources of data in addition to network packets.

Monitoring network data entering and exiting an API or application can aid in the analysis of critical network traffic indicators.

Understanding the behavior of the overall network requires mapping out the network topology. Network administrators can recognize the volume of traffic that comes in or out of each node by using network monitoring tools to keep track of the origin and destination points.

Another way to maintain tabs on everything going on on the network is to compile periodical network traffic monitoring reports. Our CDN provides a network traffic logs summary report that can be downloaded at any time from the main login page.
