What is Shared Hosting?

Shared Hosting: Definition

Shared hosting is a form of web hosting service in which multiple websites coexist on a single Internet-connected server. Your website will not be the only one stored on the server if you choose shared hosting. However, the server’s resources (RAM, processor, bandwidth, disk space, and so on) will be shared with the other websites housed there.

It’s a fairly popular web hosting option. Nevertheless, others may consider it to be too basic, but this is dependent on the demands of each website. There are currently great suppliers who can give dependable service, and you can get as comprehensive a package as your budget will allow.

How does it work?

When you construct a webpage, you must save all of the data that make it up, such as scripts, themes, text, photographs, and videos, on a server that is connected to the Network. That’s the only way for everyone else to see it.

Shared hosting distributes the resources of a single server to hundreds or even thousands of clients. This means that all of those customers share the server’s technical resources and maintenance costs. As a result, it is a very cost-effective option.

Why is Shared Hosting beneficial?

Shared Hosting is really advantageous. Here are some of its main benefits:

  1. Cost-efficient. The expense of sharing the server’s space and resources with other websites is also shared. In general, a basic plan for this service costs between $3 and $10 per month. Although initial costs may appear to be extremely low, always double-check regular prices before signing a contract. After the first year, the initial cost may increase or even triple.
  2. User-friendly. Not only can you set it up, but you can also manage its functions with only a few clicks. To administer it, you don’t need to be a skilled developer. If you are, you will undoubtedly be able to make the most of each of its features.
  3. You are not responsible for maintenance. For some budgets, the time and cost of technical upkeep can be prohibitive. That is a task that your provider is in charge of. It is not a little benefit to assist you in preventing and resolving problems.
  4. Built-in features make managing the website a breeze. cPanel, DNS administration, and a slew of other utilities make it simple.
  5. Customer service. The majority of shared hosting companies provide you with rudimentary customer service. Support can be basic or advanced, depending on the company you choose, its quality, plans, and so on.


Shared web hosting is a wonderful place to start, especially if you have a static site, a start-up, a blog, a corporate site, or something similar. It is a cost-effective and simple-to-manage option.

Choose shared web hosting only if it is the best option for your website. If your site requires more resources and you choose shared hosting, you will almost certainly run into issues.

7 most commonly used DNS record types

The DNS record types are essential for the proper DNS configuration and management. There are various different DNS record types, and each one of them is implemented for a very specific reason.

A record

The A record, also known as the Address record, is the most popular of all DNS record types. The reason for that is simple. It is used to serve the most important function. The A record links the domain name to its IP address. More precisely, it is used for IPv4 addresses. In case you have an IPv6 address, don’t worry. There is a specific DNS record for it – the AAAA record. 

SOA record

The SOA (Start of Authority) record is utilized for indicating the origin of the data. In addition, this record is contained crucial information related to the DNS zone, such as contact information about the DNS administrator and Refresh Rate. Thanks to it, the Secondary DNS servers understand when they should update their information. Every DNS zone is required to have an SOA record. Moreover, it is the very first DNS record that you should have.

MX record

The Mail eXchanger record, or just for short MX record, points to the mail server that is responsible for receiving email messages. This DNS record type is required if you want to make sure that you are going to receive all of your messages. Additionally, it prevents any issues related to spam. 

You can adjust the TTL (Time-to-Live) value of the MX record and set different priorities depending on the capabilities of your mail servers. 

NS record

NS record is another one of our list of DNS record types that is crucial to know. It serves to indicate the nameserver responsible for the DNS zone. Imagine it as the ID card of the nameserver. If you don’t have such a record, your DNS zone won’t function. Note that you should point the NS record to the nameserver.

PTR record

The PTR record becomes a necessity in case you want to send email messages without any issues. The pointer record (PTR record) is serving for the exact opposite action to the A record. It links an IP address (IPv4 or IPv6) to the associated domain name. Thanks to this record, you can implement Reverse DNS. It provides proof to your recipients that the IP address is actually related to your domain name. That way, you avoid any attempts for fraud and improve the deliverability of your messages.

CNAME record

The CNAME record serves to show which is the canonical domain name for the subdomain or domain name. In most cases, the CNAME record is utilized exactly for subdomains. That makes the DNS administration a lot more simple. Every change that you make for your domain name is going to update for each of your subdomains. You just need to create a CNAME record for your subdomains and point them to the domain name.

TXT record

The TXT record is another very useful DNS record. It contains simple text information for different outside sources. In the majority of cases, TXT record is implemented for verification and authentication purposes. That way, you can improve the level of trust in your domain name. As a result, that positively affects your internet reputation.


All of these DNS record types are used very commonly, and it is best to understand the purpose of each one of them. That way, you can easily choose and add the one you need.

DNS outage – Definition and Details

DNS outage is the time when your Domain Name System goes down for any reason (your nameservers are hit, overloaded, etc. ), and the server can’t resolve your domain name to its IP address. The first step in entering a website is to resolve the DNS. Without it, the browser won’t know where your website is located, and it won’t be able to find its content. In addition, visitors who want to access your domain will see an error message and cannot access your site.

So, we can say that a DNS outage is when website guests type your website’s name (domain name) into their device and can’t load it (they are not routed to its IP address).

What can cause a DNS outage?

  • Configuration errors. DNS outages can be caused by various human errors when configuring DNS. Script errors, incorrectly typed IP addresses, firewall configuration issues, etc.
  • The upkeep of authoritative name servers. Updates or reboots are occasionally required as part of routine maintenance. This disables the server’s ability to respond to DNS requests.
  • DDoS and DoS attacks. The purpose of Denial-of-Service and Distributed Denial-of-Service is to cause a failure of the service. You will experience a DNS outage if they succeed.
  • An occurrence in the data center (the location of the name server). The “cloud” is situated in a data center or multiple data centers, not in the sky. And while such locations are safe, they are not foolproof. Especially when it comes to natural disasters, power outages, and other issues.

How to prevent it?

Of fact, you could protect yourself against it, and there are some steps you can do to avoid future DNS outages:

  • Secondary domain name service. The most straightforward approach that could save you is to employ a secondary DNS server in most circumstances. Ideally, with a different DNS provider. The secondary DNS will let you have additional authoritative DNS servers that can still answer to queries even if the primary DNS is unavailable. The more, the merrier.
  • Load balancing. You can set up your nameservers to distribute traffic between them using load balancing. So, you can be sure that the load is not going on one of them. The performance and resilience of your DNS network will be improved by spreading the heavy load.
  • Protection against DDoS attacks. A DDoS attack is often the cause of a domain name problem. Furthermore, traffic attacks have become relatively inexpensive, and it is usual for hackers, sometimes hired by your competitors, to pull your domain down. So, what can you do? You can get DDoS protection for your Domain Name System servers that can withstand heavy load.


We can infer that a DNS outage is highly harmful and can cause significant damage to your business. Therefore, take the appropriate steps to avoid this from happening, such as implementing Secondary DNS, a Load Balancing method, and DDoS protection. This will provide you peace of mind that your Domain Name System is in good working order.

Basic Internet Terms and Definitions

Here are some of the most popular and basic Internet terms and their definitions.


The Internet is, also known as the net or web, is a global interconnected network that allows people to share information and communicate with each other. It was created thanks to the extensive progress in computing technology. Additionally, in many cases, the Internet is referred to as a “network of networks.”


The short WWW stands for World Wide Web, and it is a graphical interface for the Internet. The first time that it was introduced and available for the public was back in 1991 by Tim Berners-Lee. It is important to mention that the Internet and WWW are actually not the same things. Yet, the majority of the people still think WWW is the Internet. However, the Internet allows you to connect and communicate with your device with other devices and machines. On the other hand, the WWW is a group of web pages kept in a web server and connected to local devices through the Internet.


DNS is a short acronym that stands for Domain Name System. It is a global naming database built in a hierarchical order that stores and links all of the existing domain names with their associated IP addresses. This naming system is essential for the Internet and the overall user experience. Without it, people would be forced to use only IP addresses to connect with their favorite websites. That sounds like a memory challenge!

Domain name

The domain name is a simple text identifier that allows humans to easily find their favorite websites. Each domain name is a string of text that is unique. Due to the fact it exists, humans are able to discover devices, networks, services, computers on the Internet very fast. Two different websites could not share the very same domain name. 

IP address 

The IP address is also an identifier, yet it is numerical. The different machines and servers do not understand words. For that reason, they connect and communicate through each other via IP addresses. Due to the fact that the Internet has grown massively back in the days, the need for more IP addresses increased. That is why there are two versions – IPv4, which is the older one, and IPv6, which is the newer one.


TCP/IP stands for Transmission Control Protocol/Internet Protocol, and it combines two protocols to establish Internet communication and allow the connection between two devices that are long-distance apart.

The Internet is a packet-switched network. Additionally, the data is divided into smaller packets, transferred separately, and then reassembled at the target destination. TCP is responsible for collecting and reassembling the data packets, and IP is the component that guarantees that the data packets are transferred to the proper target location.


File Transfer Protocol, or for short FTP, is a popular network protocol. Its main purpose is to transfer files among devices and machines over a TCP/IP-based network (the Internet). Thanks to this protocol, we are able to exchange information across the Internet. The need for sharing data was very common, and the File Transfer Protocol was one of the first developments that could solve it. 


So, now you know some of the fundamental Internet terms. Additionally, now you are going to be more aware while you are browsing on the Internet of what the different components mean!
