Private DNS server – Definition & Details

April 11, 2022April 11, 2022 Mario No Comments

Our topic today is the Private DNS server. Have you ever heard something about it? If not, don’t worry. You have come to the right place. Today we will explore its main purpose and why it is so beneficial. But first, before we go on to the Private DNS server, let’s define the Domain Name System (DNS).

What is DNS?

The Domain Name System, or DNS for short, is a decentralized namespace that is organized. Its major goal is to help users browse inquiries, discover the host they’re looking for, and respond swiftly. The DNS was created in the 1980s to replace the wasteful HOSTS.txt file, which contained all of the current hosts. Because of its scalability and speed, DNS is superior.

In a nutshell, DNS is a service that maps domain names to IP addresses and may also be used to map services to hosts, verify distinct hosts and services, and so on.

Authoritative DNS server – everything you need to know

April 4, 2022June 16, 2022 Mario 1 Comment

The world of DNS is complicated, and there are a lot of small details that we should think about. The DNS is a mechanism for domain resolution. The whole system involves many different DNS servers on different levels – root, TLD, domain name, subdomain. Now we will talk about the authoritative DNS server of the domain name level. Why do you need it, and what it does.

In the following article you can find additional information about Authoritative DNS Servers!

rDNS: What is it and how does it work?

January 21, 2022January 21, 2022 Mario No Comments

The rDNS (Reverse DNS) process is only one aspect of the Domain Name System’s operation. The purpose is to connect an IP address to a domain name. It’s a tool that can be used in both the IT and business fields.

rDNS – meaning

As we know, DNS is the process by which we use a domain name to reach its corresponding IP address. Reverse Domain Name System or rDNS is a procedure where you use the IP address to get information about the domain name. So this process is the opposite of standard DNS resolution.

Recursive DNS server – an overview.

August 10, 2021August 26, 2021 Mario No Comments

Domain Name System (DNS) is a great invention no matter its credit is not always recognized. And that is because it’s absolutely needed but invisible for regular users. But the situation is different for network administrators, IT teams, and online business owners. They all know that to make websites, and other resources accessible for people means profits for them.

There is no gain without Domain Name System functionality. Everything you want to offer online, from content to products or services, needs to be shown through websites. And to load them for clients can’t happen without the DNS resolution.

We can talk long about DNS functionality, but let’s focus this time on one important DNS component, the recursive DNS server.

What is DNSSEC?

July 24, 2021July 27, 2021 Mario No Comments

You can see DNSSEC as a patch to otherwise unsafe DNS. It brings cryptography to the table and a whole line of trust, which guarantees every level and provides top-notch security for your domain.

What does DNSSEC mean?

The whole meaning of DNSSEC is a mouth full – Domain Name System Security Extensions.

The original DNS is fast and reliable, but it lacks security. It wasn’t that of a problem when it was first created. Later, in 1993, the Internet Engineering Task Force (IETF) finalized specifications for DNS data encryption standards. It got in use in 2005, and its latest revision is from 2010.

The DNSSEC aims to stop the DNS cache poisoning and alteration of the DNS data that could happen if it is not activated.

The DNSSEC involves all levels of a domain, including the root, TLD, and the part that you can manage.

It uses a combination of public and private keys, where each upper level can verify the level below.

It is a chain of trust. If one level fails, the chain is broken, and the data cannot be trusted.

Why do we need DNS Failover?

Every website or network owner knows that having an alternative plan in case of an outage is a must. There are different ways to get redundancy not to be affected if a server is attacked, down due to maintenance, or broken. Usually to have not one, but more alternatives to guarantee your up-time are totally welcome.

This said, DNS Failover is a technology you should understand and consider for your business.

Round – Robin DNS explained

April 21, 2021August 26, 2021 Mario No Comments

Round-Robin DNS is a simple mechanism for managing DNS load balancing. This task is not done through hardware but via a DNS server known as an authoritative nameserver.

When you deploy Round-Robin in a DNS server, this will save different A records. Each of them has different IP addresses, but all with the same domain name. Every time this DNS record is requested, it will deliver a response (IP address) by its order. And every IP address used to respond to a request will be put at the end of a line to be used again. You have multiple IP addresses working on a constant rotation cycle.

This mechanism is really useful if you have your website’s content hosted on different redundant servers located at separate points of the globe. The authoritative nameserver will use this rotation cycle to answer with a different IP address. By doing so, it will load balance the traffic.
