Most likely, you’ve heard the phrase “DNS propagation,” but you’re not really clear what it means. You’re not alone, so don’t worry. In that way, in this article, we will give a simple explanation of DNS propagation.

What DNS propagation means?

The act of updating and disseminating all of your new changes to the Domain Name System is known as DNS (Domain Name System) propagation. And it’s all over the internet.

If you manage a network or own an internet business, you are aware that the DNS needs to be changed frequently. For example, a DNS record may need to be updated, a new one added, or it may need to be edited to replace IP addresses.

​How does Dynamic DNS work?

If you are an administrator of a network and you still don’t use Dynamic DNS, convince your boss to get it today! Yes, it will give you a hand you need and time to breathe! To administrate networks is a really tough job. Try to make it easier when possible.

DNS resolution: Essential Process You Should Know

Today’s article will explore the DNS resolution – its purpose, how it works, and why it is critical for you and your business. So, if this sounds interesting to you, let’s take deep into Domain Name System resolution.

DNS resolution – Definition

DNS resolution is the process of translating a domain name into an IP address (IPv4 or IPv6). Without it, the Internet would function in a very different way. However, it occurs behind the scenes because typical consumers are unaware of the situation. People are accustomed to inputting a simple domain name into their browser, which loads the appropriate website. However, the user’s DNS query is routed via numerous servers before receiving a complete response.

FQDN – What is it and when to use it?

FQDN is an essential part of the Domain Name System. If you want to learn more about it, you are in the right place. In this article, we will see what it means and why it is important. 

FQDN – meaning

The term “Fully Qualified Domain Name,” or FQDN for short, is a domain name that specifies its exact location in the Domain Name System’s tree structure. It is also sometimes referred to as an absolute domain name. Every domain level, including the top-level domain and the root zone, is specified. It is the most thorough method of composing a specific domain name for a host or device.

A record: Fundamental DNS record you should know

The most popular and most commonly used DNS record is exactly the A record. But, if you are just starting managing your network and you haven’t heard about it, don’t worry! Here is a little bit more information about it!

A record explained

The A record, also commonly known as address record, is a DNS (Domain Name System) resource record. It has the essential purpose of linking a domain name to its IP address (IPv4 address). Therefore every time a user desires to connect and explore a specific website, its browser is going to require the IP address which is provided with the A record. Thanks to it, it is going to understand exactly where that website is hosted and connect to it without any difficulties.

As we mentioned, the A record holds inside an IPv4 address, a 32-bit address that includes four combinations of digits divided by dots.

What is a Secondary DNS and why is it used?

It’s a great idea to use the Secondary DNS to keep a reliable copy of your data. You’ve most likely come to our post because you’ve heard about it and want to improve your DNS’s reliability. Yes, Secondary DNS can provide peace of mind, especially in today’s world where DDoS attacks and other DNS difficulties are widespread. So let’s go over the facts and explain things a little more.

Authoritative DNS server explained

There are different types of servers – TLD, root, recursive, authoritative DNS server etc. If you think that all of them are the same and comply with the same objectives, that’s a mistake. They are teammates, but definitely, there are differences between them. Today let’s talk about Authoritative DNS servers. What exactly are they for? Why do you need them? Here it will be explained! 

What is an Authoritative DNS server?

An authoritative DNS server, also known as Primary DNS server, is the holder of the zone file that contains the DNS records. And in this case, we don’t talk about a copy of them but the true DNS records. For this reason, it’s the exact and only place the master zone can be managed from and where edition or any kind of modification to DNS records can be made.

A complete breakdown of Anycast DNS

We will show you everything you need to know about Anycast DNS. A complete breakdown of Anycast DNS that will explain to you the functionality and purpose of this service. 

​What is Anycast?

Anycast is a routing scheme that is perfect for use with DNS. You can use the same IP address (Anycast address) on multiple nodes. It is more about the configuration of routers and routing than servers. 

Each packet sent to an Anycast IP address may reach a different server in an Anycast DNS scenario. The anycast address is shared or configured in multiple different servers across the network. 

They are routed to the IP address with the best network metric. This is the nearest server in most cases, but it is not a must. The metrics could be various factors like bandwidth, cost, load, or reliability, etc.
