If you came to this article, you maybe want to learn more about the DDoS attack. So, yes. Here you will find the fundamental information about it. In addition, and more specifically, we will look at the purpose of this attack, how it function, and what are the methods to prevent it. So, if this matches your desires, let’s start exploring it!

DDoS attack purpose

A Distributed-Denial-of-Service (DDoS) attack is a type of cybercrime. It means that the goal of a DDoS attack is to overwhelm a server, computer, or network with massive amounts of traffic generated from multiple sources. When the target fails, its services or access to it for regular users is denied.

Email forwarding explained

Email forwarding

At first sight, it seems there’s no so much to explain. Currently, most people have an email account. Therefore we know what it is to forward an email. Many times, after receiving a message, we have resent it to another friend or friends for sharing its content. But we don’t mean that basic operation. Email forwarding has much more in store for you and your business. 

What is email forwarding?

Email forwarding or domain email forwards is a mechanism for automatically redirect emails on the domain level. Emails can be redirected from an email address to another or from many different email addresses to a specific one. Time is a factor you can freely define while getting the service, meaning you can execute this operation permanently or during a short, medium, or long period of time.

DDoS protection

DDoS protection is crucial for any online organization that focuses on staying online. It provides a guarantee that your service or website won’t be affected if a DDoS attack is initiated. So, let’s explain a little bit more!

DDoS attack – definition

The goal is to exceed the capacity of the resources and make the victim unable to answer requests of the regular customers. Then, finally, the victim gets completely unable to operate.

Usually, DDoS attacks are initiated towards:

  • Websites for online shopping

Ping command – How to use it?

Ping command

Ping command – Definition

The Ping command is a small and simple utility tool with a command-line interface (CLI). It is very helpful for network diagnosing and probing a specific host or IP address (IPv4 address or IPv6 address). When you use the Ping command, you actually send data packets utilizing the ICMP (internet control message protocol) from your computer to a target. By default, the packets are going to be 4 each with a 32-byte size. Moreover, you will receive the time it was needed for each of them to reach the target. The statistics will also show you the minimum, maximum, and average time (in milliseconds) required for the road. Another interesting piece of information is the portion of lost packets, and of course, you will receive the IP address of the target.

In brief, the Ping command transfers data packets from your computer to a target and expects the packets to bounce. When they come back, you can see the statistics.

What does TTL mean?

TTL

TTL – meaning

Time To Live (TTL) is the value that indicates how long the data should be stored in a particular device. A lot of data pieces hold their own TTL value.

If we speak about DNS TTL, it refers to the time the DNS resolvers have to store the DNS records in their cache memory. Every DNS record also has its own TTL value. Some of them have longer TTL because the chance is less for the value to change. Yet, others have shorter TTL values, where changes more often happen. 

Here is a basic illustration of values as an orientation for your DNS records:

  • A and AAAA records – 2 hours (7200 seconds)
  • CNAME records – up to 12 hours (43200 seconds)
  • TXT records – up to 12 hours (43200 seconds)
  • MX records – 1 hour (3600 seconds)

DMARC record – Why is it important?

DMARC record

As a domain owner, for sure, you should consider implementing the DMARC record. When you own a website, it is essential to build a trustable connection with your customers. That includes ensuring them that the emails they receive are sent from you and not someone else. 

The conversation between you and your visitors must remain transparent. So, let’s explain a little bit more about the DMARC record and why it is so important!

DNS SRV record explained

DNS SRV record

Let’s investigate one more complicated DNS recourse record, the DNS SRV record. It is a very important one that points not only to the service, its location but also the exact port that it uses for communication. Let’s see the DNS SRV record in detail.

What is the DNS SRV record?

The DNS SRV record (service record) is a DNS record that is used to show the service’s port and hostname. What makes it different from other DNS records is that it specifies port too, and not the only hostname. That way, you can set through which port you want to be used a specified service.

What is ccTLD?

ccTLD

Are you planning how to succeed on the Internet? To plan strategic moves sometimes requires diving into lots of abbreviations, terms, technology names, processes, etc., a little bit hard to understand. So, if you got stuck wondering what ccTLD is, here you have the explanation.

What is TLD?

TLD means top-level domain. Domain names have a clear structure. Each of its components is separated by a dot. On the left, the subdomain is located. Then the SLD or second-level domain comes. This component is easy to recognize for everybody because it’s the name of the business or brand the domain is about. Then, finally the TLD, that also is easy to identify since most extensions have become really popular: .org, .com, .gov, .uk, .net, etc. There is a “.” after it that represents the root domain, but this will be for another time.

Actually, you are very familiar with this structure. Just see this example: www.example.com. On the left, you have the subdomain “www”, “example” is the SLD, and finally, the TLD is “.com”. 

The structure obeys the DNS (domain name system), the international system used to translate domain names to IP addresses for the Internet.

What is an MX record in DNS?

MX record

The Domain Name System (DNS) is a complicated solution that links domain names to their IP addresses. The purpose is to make it easier for people. We remember names that we can easily write and keep in our memory and get to sites, that we need to know their location on the network – their IP addresses.

The DNS works with text commands that computers understand. These commands are called DNS records, and they are saved on DNS nameservers. In our case, we will explore the MX record and what other types of records you will need with it for a functional mail server.

SSL vs TLS. Which one to choose?

SSL vs TLS

Authentication and security for the transporting of data are the common factors between these two technologies. There are differences between SSL vs TLS. Let see what each of them has in store for you.

What is SSL?

Secure Sockets Layer (SSL) is a standard for encrypting data that is exchanged between users’ devices (browsers) and websites. SSL also proves identity for users to feel safer. SSL became a convenient security layer, especially for websites requiring sensitive data from users.
