We just started to chat about DNS records with the DNS A Records, and now we will see a second DNS record – DNS MX record. MX does not mean Mexican. It means Mail Exchanger. We will go into details about why such a DNS record must exist and why can’t we freely send emails the way we want.
Every action that relates to domains needs DNS records for instruction. In the DNS MX record case, it is a text document, mail exchanger record, that shows which server is responsible for receiving the emails that go for a particular domain.
IPv4 and IPv6 are two different versions of Internet protocol (IP). For that reason, it is important to understand what are the differences between them. So, let’s explain a little bit more!
Internet Protocol (IP) – What is it?
Internet protocol, or as we know it, more popular as IP, establishes a group of communication rules which control the format of the information transferred among the networks or the Internet.
Thanks to the IP, it is easy to set the most suitable structures for packets to transport data until they are delivered. In addition, it includes several methods for addressing, and it routes datagrams across networks. Therefore, the transportation of data packets from their origin to their target destination depends on IP addresses.
When it comes to connections on the Internet, it is crucial to know who is requesting some data and who is supposed to provide the information, like routers, websites, servers, Internet of Things, and so on. IP addresses serve for identifying and connecting with the machines, devices, servers. That makes it possible to achieve communication and exchange of information.
What is domain parking? Domain parking is a service (usually free) that domain registrars offer to their clients (people who got themselves a domain name) to have a simple, non-interactive, single HTML page, where the clients can put their contact information and a short text message with more details about the future of the domain...

Domain Name System (DNS) includes many different records to execute different functions required for the Internet to work as easily and efficiently as users expect. TXT records’ functionality is absolutely essential. Check out why to use TXT record. What is the TXT record? Text or TXT record is a DNS record that holds text information...

In the last years, cloud computing services have become very popular. But still, while chatting with colleagues, some confusion comes around the term and the kinds of services that it involves. What is cloud computing? Shortly, cloud computing is an on-demand supply of tech resources through the Internet in exchange for a defined fee. Rephrasing,... Continue reading: What is IaaS?
Understanding DNS record is easy. The only thing that you need a simple explanation. We will see what a DNS record is, and we will start speaking about one of the most used ones – DNS A record. It is the simple record that connects what you are typing in your web browser and the address of the site, but let’ go in-depth.
A long, long time ago, there was no Internet! Can you believe it? Back then, there were just a few university computers and some military ones linked together through different networks. They were working together, but with a lot of connection problems. The number of the devices started to grow, so did the connection between them.
Back then, each of the computers needed to have a hosts.txt file on their memory, which was basically a table with hosts’ names and their IP addresses. Like a table of A records, but of all possible devices that are there.
Imagine having to administrate a massive excel table with all the sites that you want to visit and their addresses. A lot of work!
The hosts.txt was not a viable option, so there was a need for a better system for that new thing called the World Wide Web. This is where the Domain Name System came.
To keep running a network demands dividing administrators’ attention and time among many tasks. All are necessary. Some are really exciting. And others… Well, no job is perfect. Others can be really boring, and besides, they can require a lot of time.
Fortunately, technology is focused not only on developing new and amazing stuff but also on making daily and boring tasks easier, sometimes automatic. And that is the case of DHCP.
TLD means Top Level Domain, and it’s the suffix of a domain name.
A domain name is built with three parts, each one separated by a dot. The subdomain is on the left side. The second-level domain (SLD), brand, or a name that states the kind of business you have, comes in the middle. And the top-level domain (TLD) is at the end (.com, gov, .org, .net, .de).
Example: www.speaking-easy.com, “www” is the subdomain, “speaking-easy” the SLD, and “.com”, the TLD.
How many of you have felt their device slower, struggling to perform even a simple task? Or maybe worst, the device gave all your personal data away or was completely locked from malware.
Computer viruses are modern nightmares, a big danger, but they started as a silly prove of concept. The goal was to prove they can exist, not a real profit. Can you guess when the first virus was created?
