Basic DNS terms you should know.

If you own or plan to start an online business, congrats! You got an ambitious and exciting mission that only the bravest and smartest can comply with. But, to make it, there’s an inevitable step: you must conquer the DNS world first! 

Start your ninja training now, understanding some of its basic DNS terms.

Domain Name System (DNS).

The first on the list of our DNS terms, of course is the Domain Name System. It is the great solution to make the use of the Internet as easy as it’s now. It’s a very helpful database that translates domain names into their corresponding IP addresses to be found and loaded.

Before finding a host was done through its IP address, a numerical string like (IPv4) or 1580:cb11:2045:1::c530:d6a1 (IPv6). 

Numbers are great and easy for machines to communicate and execute their processes, but this was not too simple for humans. Imagine memorizing the IP address of every website you want to visit! Therefore, this system was created for hosts to have catchy names, easy for humans to remember, like

Domain name.

The second one in our list of DNS terms is the domain name. It is a line of text for mapping an IP address. It’s used for accessing websites by typing easy and memorable names instead of their corresponding numerical addresses, called IP addresses. You type, instead of 1580:cb11:2045:1::c530:d6a1.

IP address.

An IP address is a line of numbers, divided by periods, used to identify websites, computers, and routers. Every IP address is unique, and it’s mathematically created and allocated by IANA, the Internet Assigned Numbers Authority.

IP addresses hold location information vital for finding and identifying machines. Besides, they are needed for devices to communicate and exchange information on a network.

DNS query.

A DNS query, also known as a DNS request, is a petition of DNS information that a user sends to a DNS server via his or her device and browser. The most common DNS query is the one you send every time you want to visit a website. You type a domain name, and a DNS query to get the associated IP address of such domain is sent to a DNS server. Without this information, the website can’t be loaded for the user. 

DNS records. 

The DNS records are simple text files hosted on the authoritative name server and have instructions about the domain like its IP address, the services that a host uses, records for authentication purposes, and more. 

An example of one is the A record that connects the domain name and its IPv4 address. 

Authoritative name server.

An authoritative name server is the type of server that holds all the DNS records of a domain name and other web resources. Once a DNS query has been sent, a process to get the necessary IP address for loading a domain name starts. And an authoritative name server is the last server that participates in such a process. It’s the one that will deliver the A record that contains the IP address.

Recursive server.

A recursive server has a searcher vocation. Every time a DNS query is sent from a user’s device, this server will take it, and it will start a searching process in which it will query different servers until it gets the DNS data needed to answer such query. When it looks for the associated IP address of a domain name, its goal is to reach the authoritative name server, to finally obtain the A record that contains that IP address.

Recursive servers can cache the results of their searches for a period of time defined by the TTL (time-to-live) of every DNS record. If the information queried is not saved in its cache anymore, it has to do the whole searching process again by querying other servers. 


DNS has its own and very specific rules and processes. However, if you want to survive and successfully complete your mission, this is a good starting point! Success, DNS ninja!

Domain flipping explained

What does domain flipping mean?

Domain flipping is an interesting type of business. The goal is to buy domains at a low price and make a high profit after selling them later. If you want great deals, you have to be able to consider which domains have potential. Such domains have to be possibly interesting for particular clients, which can provide a high-value offer.

Regularly, a new domain extension is released. So, the amount of available domains is enormous. This is a reason why domain flipping has such a boost. A lot of people make a side job from this business. But, others took the opportunity to go further and make domain flipping their main source of income. So, if you want to try it, you can get extra money from it. Let’s see how you can start.

How to start?

1. Your strategy is first

Before you start implementing it, you have to consider what is your strategy. First, think about how you desire to be involved? Is this going to be your main business or a side income? What is the amount you will invest? Then, you can decide which way to go. You may want to buy a lot of cheap domains and gain small earnings. Or you can go in a different direction and purchase fewer domains, but more attractive. They can be more expensive in the future.

2. Domains with potential

The ways to purchase domains are various. The important thing is to choose the right ones. Things like popular keywords and catchy phrases are essential when creating a domain name or selecting a potential one. Basic SEO knowledge helps with recognizing profitable names. Also, you can use a tool to assist you in discovering such domains. Another method that you can pick is through domain auctions. 

Check the domain’s cost to ensure that the deal is like you expect. Things that determine what profit you will get are brand-ability, memorability, length, and searchability.

3. Act fast 

If you find one or more options that seem completely profitable, buy them through a registrar. Don’t forget that many people are in the business. So, don’t waste your time and allow others to buy and register them first.

If the domain you choose is available online, you can proceed to register it. In case it is already in use, it is possible to purchase it from the owner. Just make a reasonable offer. The other way to get it is to wait for the current ownership to expire. 

4. Don’t hide your domains 

You have to make sure that the world knows about the existence of your domains. Look for clients. Promote it on the site by adding your contact information. You can offer directly to potential clients. Another way is to put it in forums, social networks, and auction sites.

5. You should be patient

Patience is a must for making a great deal. Domain flipping is a process, which requires time. Of course, you can complete a deal in a short period of time. But honestly, that may not happen daily. For quicker profits, the auction sites are a great place.

6. Resell

The final step is the most important one. Once you have a buyer and the offer is suitable for you, the last thing is to transfer the domain ownership, and the domain flipping process is complete.

Fully Qualified Domain Name (FQDN) explained.

What is FQDN?

FQDN is the short acronym for Fully Qualified Domain Name. With it, you are able to see precisely the most full name of a specific domain name. And that refers not only to websites but also to servers. The Domain Name System (DNS) is created with a hierarchy order. It starts from the top, which is the root, then TLD, after that the domain, and the last is the specific hostname.

Here is the full syntax of a fully qualified domain name (FQDN):

hostname. domain name. TLD 


Let’s view an example of a fully qualified domain name (FQDN): 

Be aware that the dot “.” (root), which is last, is often neglected. Usually, the fully qualified domain names end with the TLD. However, there are cases in which you will need to add it. That depends on what software you are using.

The Fully Qualified Domain Name is suitable when you want to view where precisely an object exists in the Domain Name System hierarchy.


Here are the 3 elements of Fully Qualified Domain Name formatting. 

  • First is the TLD (Top Level Domain) – It is represented with the ending signs that we can see in an FQDN. Commonly 2 or 3 characters, such as .com, .edu, .net etc.
  • Subdomain – It is the domain that we can observe below the Top Level Domain. For example,
  • Hostname – It is represented with the symbols placed at the beginning of the FQDN. The most popular example is www in A domain owner can generate many hostnames as they are associated with a subdomain. For example:

How to check the FQDN?

If you want to check if your device has an FQDN or its hostname is an easy task. It doesn’t matter if you are using a Windows 10, Linux, or macOS device. 

On Windows 10

  1. From the start menu, open your “Control Panel.” 
  2. Inside the Control Panel, open the System. 
  3. Inside the System, view the “Device specifications” and search for the “Device name”. 
  4. Next is the FQDN. 

On Linux 

  1. First, open the Terminal application. 
  2. Simply write this command: “hostname -f.”
  3. Press Enter, and you will see the FQDN. 

On macOS:

  1. First, open the Terminal application.
  2. Write down the command: “hostname -f.” The option “-f” means full. 
  3. Press the Enter, and you will see the FQDN. 

Why do you need FQDN?

The FQDN represents a unique address on the Internet. It is vital to the experience online. Imagine it, like you don’t have an FQDN. It is like you don’t have a website for people to visit. 

You will need FQDN if you want to install SSL certificates. This is because most websites are expected to have such a feature. 

With FQDN, you can access domain services, for example like email and File Transfer Protocol (FTP). If you want to connect a domain name email to an email app on your device manually, you will need the FQDN.
