Monitoring service is crucial for providing a reliable service and a great user experience. In addition, it serves to identify issues regarding your services like web, DNS, email, and so on. Thanks to it, you receive detailed data about the conditions of your servers, and it helps you find and fix different problems quickly.
Have you ever wondered how your web browser is able to find the correct website you want to visit, despite the countless domains out there? The answer lies in the Domain Name System (DNS), a crucial system that helps translate human-readable domain names into machine-readable IP addresses. Within the DNS infrastructure, Authoritative DNS servers play a key role. In this blog post, we will explain Authoritative DNS servers and shed light on their significance for beginners.
Before diving into Authoritative DNS servers, let’s have a quick overview of DNS itself. The Domain Name System is like the internet’s phone book, linking domain names (e.g., www.example.com) to their corresponding IP addresses (e.g., 192.164.0.1). This translation happens behind the scenes when you enter a domain name in your browser’s address bar.
To learn the concept of Authoritative DNS servers, it’s essential to understand the hierarchical structure of the DNS system. At the top of the hierarchy are the root servers, which maintain information about the top-level domains (TLDs) such as .com, .org, .net, and so on. Beneath the root servers are the TLD servers, responsible for specific domain extensions. Further down the hierarchy are the Authoritative DNS servers, which hold the authoritative information for individual domain names.
An Authoritative DNS server is the final authority on a specific domain name’s IP address. When a DNS query is made for a domain, it first reaches the recursive DNS resolver, usually provided by your Internet Service Provider (ISP) or a third-party DNS resolver. If the resolver doesn’t have the answer cached, it begins the resolution process by reaching out to the Authoritative DNS servers.
Authoritative DNS servers are responsible for storing and providing the IP addresses or other relevant DNS information for a specific domain. They act as a trusted source of information, enabling users to find the correct IP address associated with a given domain name.
Often, a domain has Primary and Secondary Authoritative DNS servers. The primary server is the main source of authority, holding the most up-to-date information about the domain. In addition, it is responsible for responding to DNS queries and updating the Secondary servers with any changes.
Secondary Authoritative DNS servers serve as backups, ensuring redundancy and improving overall system reliability. They synchronize with the primary server and can take over DNS resolution if the primary server becomes inaccessible or experiences issues.
Time-to-Live (TTL) is an important aspect of Authoritative DNS servers. TTL determines how long the DNS information retrieved from an Authoritative server can be cached by other DNS resolvers or clients. A shorter TTL means that DNS resolvers and clients will get updated information more frequently. In comparison, a longer TTL reduces the frequency of queries, improving performance but potentially leading to longer DNS propagation times for changes.
Authoritative DNS servers form the backbone of the Domain Name System, enabling the translation of domain names into IP addresses. They serve as the final authority on a domain’s IP address, ensuring users are directed to the correct websites they seek. Next time you enter a domain name in your browser, remember these DNS servers’ significant role in delivering the information that seamlessly connects you to your desired website.
Today we will explore the Private DNS server. This is one really important component for your network business security. But first, let’s explain what DNS server means.
To start explaining what a Private DNS server is, let’s see what does DNS (Domain Name System) server means briefly. In 1983 it was created, and 3 years later, it became one of the original Internet Standards. It is a part of the DNS resolution process. That means it helps to translate human-friendly URLs into computer-friendly IP addresses. So, it turns clearwire.ie to 185.138.164.55 and vice versa.
DNS outage is the time when your Domain Name System goes down for any reason (your nameservers are hit, overloaded, etc. ), and the server can’t resolve your domain name to its IP address. The first step in entering a website is to resolve the DNS. Without it, the browser won’t know where your website is located, and it won’t be able to find its content. In addition, visitors who want to access your domain will see an error message and cannot access your site.
In this article, we will focus on one really interesting topic, which is Whitelisting and Blacklisting. First, we will explain what Whitelisting is and then what Blacklisting is. Finally, we will make a comparison between them. So, let’s start.
Shared hosting is a form of web hosting service in which multiple websites coexist on a single Internet-connected server. Your website will not be the only one stored on the server if you choose shared hosting. However, the server’s resources (RAM, processor, bandwidth, disk space, and so on) will be shared with the other websites housed there.
Have you ever heard about Dynamic DNS? It is an absolutely incredible service. Why? Because it lets you connect to your gadgets over the Internet using a simple domain name. In our article, we will take a detailed look at it, how it functions and why it is so beneficial.
Dynamic DNS (DDNS) stands for Dynamic Domain Name System. It’s a great way to update your name server automatically and regularly. Whenever they change, it changes IP addresses and their related A (IPv4) and AAAA (IPv6) records. It saves you the time and effort of manually doing this process.
An amazing Dynamic DNS service that is worth your attention!
The DNS record types are essential for the proper DNS configuration and management. There are various different DNS record types, and each one of them is implemented for a very specific reason.
A DDoS or Distributed-Denial-of-Service attack is a form of cyber attempt. It means that the goal of a DDoS assault is to overload a server, computer, or network with massive amounts of traffic generated from various sources. Then, when the target fails, its services or access to it for regular users is denied.
Here are some of the most popular and basic Internet terms and their definitions.
