DNS propagation – What is it?
DNS propagation is a complex process involving the update and spread of new modified information across the network of servers. Whenever you make a change in your DNS, for instance, create a new DNS record or edit an existing one, it is going to be saved in the authoritative DNS name server.
However, the network contains numerous DNS servers, such as the recursive ones, which are spread in different geographical places all over the world. Therefore, each server on the network has to receive the updated changes to function correctly in the process of DNS resolution.
The time required for distributing the changes to all of the different recursive servers is the DNS propagation.

IPv6 full definition
The sixth iteration of IP, or the internet protocol, is IPv6. In order for a device to send and receive data from a host to a destination, it must abide by a set of rules known as IPs. We require identifying hosts, their geographic coordinates, IP addresses, and a communication path.
Back to IPv6, which has been around since 1995 forever! The odd thing is that there has been a shortage of available IPv4 addresses, along with other issues. Even still, the majority of companies continue to utilize IPv4. Furthermore, it is now a recognized Internet Standard (IETF) that Internet Protocol version 6 usage will soon begin to increase.
GeoDNS is an absolutely helpful service that you could benefit from. In this article, we will take a deep look at its main purpose, how it functions and why it is so advantageous. Let’s start!
GeoDNS – Definition
The GeoDNS stands for Geographical Domain Name System and is an effective traffic distribution method. It works by responding to requests based on their location. It’s also called a traffic director or a global traffic director.
GeoDNS is an excellent solution for load balancing and optimizing traffic to domains. As a result, problems are decreased, and networks are strengthened due to their utilization.
Large volumes of traffic necessitate large-scale solutions. If you operate a global company, GeoDNS is a must-have. It will provide you with all of the essential name servers in strategic locations across the world to meet your needs and markets.

UDP is the main topic of your article. We will take deep into its purpose and how it functions, and we will look at the relationship of UDP with DNS. So, it sounds interesting to you, let’s start!
Definition of UDP
The abbreviation UDP stands for User Datagram Protocol. It’s a well-known communications protocol that offers a fast solution. We use it to connect diverse Internet services with low latency and loss tolerance.
The User Datagram Protocol allows data to be transferred before the recipient agrees, which speeds up the communication process. Consequently, User Datagram Protocol is the preferred method for time-sensitive communications such as DNS lookups, Voice over IP (VoIP), video, or audio transfers.
What is CDN?
CDN is the short acronym for Content Delivery Network, and it represents a large network of servers that are spread across different geographical locations. The main purpose of these servers is to cover a territory well and provide fast answers to the requests of potential users. All of the servers store the needed information, like images, video, code, in their cache memory. Additionally, they aim to be as close as possible to the users. As a result, the service is way more improved and quicker. Moreover, an extra positive effect of the CDN is load balancing. It improves the performance and reduces the load on the primary server.
SaaS, PaaS, and IaaS are the primary three types of cloud computing as-a-service choices. Every one of them covers a different level of management for you. So, let’s explain a little bit more about SaaS, PaaS, IaaS, and cloud computing and how you can use them to build an environment that satisfies all of your needs.
Cloud computing – definition
Cloud computing is an on-demand supply of various computing services or resources through the Internet in exchange for a defined fee. That way, you can get all the things you need, such as data centers, servers, storage, databases, software, security, really quickly and without the necessity to actually own them.
For sure, cloud computing entirely changed the model of receiving these services. It lowers the operation costs of many customers because they are not required to purchase and maintain data centers and numerous services.
Email forwarding is a very useful tool for your business. This is a quick and straightforward method to automatically redirect all emails that are going to a particular mailbox. What is the process behind it, and how useful it may be we will see in today’s article.
DNS cache – Definition
The DNS cache represents a cache memory for storing DNS data (DNS records) for particular domain names only for a short amount of time. This type of memory mechanism could be found in various devices, machines, smartphones, computers, DNS recursive servers, and more.
Many of you came to this article because you want to make available a particular service from your home or office on the Internet. Dynamic DNS will serve you this purpose! It is easy to implement, and it will save you money, and it could even be free if you don’t require a lot of resources. Do you want to learn more?
What is Dynamic DNS?
Dynamic DNS (DDNS) is a DNS service that allows you to create a hostname for a device and link it to its IP address. It is a simple A or AAAA record so far. The Dynamic part comes from the fact that you can set up your router to report changes in this device’s IP address and send an update message to the DNS server where the link was made. There the hostname’s IP address will be updated. It is a way to automatically update the IP address of a device and provide availability with the need of human effort. You can set up the Dynamic DNS and be sure that the service you are running will be available.
Many of you might be too young to remember, but using FTP was a common way to download files back in the 90s. FTP servers were data sources, and you could download files with an FTP client application. Yes, the FTP protocol is “ancient”, but it is still around. Do you want to learn more about it?
What is FTP?
FTP (File Transfer Protocol) is one of the standard communication protocols that have the purpose of transferring files from a server (FTP server) to a client (FTP client). As you can see, it uses a client-server model of communication. The client needs permission to establish a connection. That could be a login (user name and password), or the FTP server could be public and open for everybody without authentication.
