How does Dynamic DNS help your online availability?

What is the Dynamic DNS concept?

To begin, Dynamic DNS, also known as DDNS, is a service that immediately updates your IP address (the A or AAAA record) if the host (device) changes it.

When the lease on your IP address expires, your ISP (Internet service provider) can change it automatically.

If you use the device as a server, you can use DDNS to ensure it remains accessible. Otherwise, you won’t be able to reach or determine the new IP address from afar.

Without Dynamic DNS, the connection would break the moment the ISP changed the IP address, making it impossible for someone operating a monitoring server with a camera at home to observe the footage from a distance.

What is the process of Dynamic DNS?

When using Dynamic DNS, you should pick a trustworthy DNS hosting company that provides the service. Once you’ve located the service that best meets your requirements, you should install its software on the router or host device. If the ISP changes the IP addresses (IPv4 or IPv6), this specialized program contacts the Dynamic DNS service provider. The DNS hosting provider then modifies A record or AAAA record by swapping the old IP address for the new one.

There is no way to use a DDNS service when a network is configured with a static IP address. The reason for this is straightforward. There is no need for additional changes once a domain name with a static IP address is requested. Why? Because these IP addresses are static. They are, however, costly.

How beneficial is this service?

Among the benefits that DDNS can provide are:

  • A straightforward solution. All you have to do is sign up for the service, and the software will be installed. Ready!
  • DDNS is a low-cost option. There are both paid and free DDNS providers. However, it is less expensive than purchasing static IP addresses for your company’s devices.
  • You will receive real-time notifications for IP changes to the DNS server.
  • A strong and reliable Internet connection is necessary to install security cameras. They will continue to operate continuously because of Dynamic DNS.
  • Access should be simple and seamless for employees who work remotely or use a VPN.
  • Access to your server or website is not interrupted. It makes no difference if the IP address changes. Your visitors will be able to access your website.
  • You will notice the benefits of Dynamic DNS if you use your computer to host an app, game server, or website.

Conclusion

Just now, you learned what Dynamic DNS is, what is the way it works and which are its key benefits. Do you want to utilize it? Consider using it since, for the most part, it will function well and save you money. And in addition, if you cannot afford downtime, carefully consider which DNS hosting provider to use.

5 Critical Internet Terms You Need To Know

The topic of our article is the most basic Internet terms and their definitions. To begin with, the Internet is a collection of decentralized networks connected by a system of protocols referred to as TCP/IP. Therefore, the more extensive network enables the communication between computer networks operated by businesses, governments, universities, and other organizations worldwide. We will also define some basic phrases used on the Internet to help you understand this. So let’s start.

Web Browser

The first Internet terms from our list are web browsers. Why are they essential? Many individuals mistakenly believe that a web browser serves as a search engine, but in reality, a browser is computer software that facilitates access to the World Wide Web. Every web page, image, and video on the Internet has a particular Uniform Resource Locator (URL), which enables the browser to recognize the resource and download it from the web server. This is how browsers function. In conclusion, it is client software because it operates on a user’s computer or mobile device and communicates with the webserver to obtain the information the user has requested. In addition, the ability to store downloaded files, music, and movies via an integrated FTP client is also available in web browsers.

IP address

The Internet’s anchors are its IP addresses. They support your entire digital life and connect you to the Internet. Furthermore, IP address stands for Internet Protocol address. It is a set of numbers that are given to each device linked to the Internet or a computer network. For instance, it is 5.181.27.75. This example is an IPv4 address, although IPv6 addresses are also possible.

Domain Name System (DNS) 

Since names are more accessible for people to remember than numbers, the Domain Name System (DNS) is best recognized for connecting domain names (hostnames) with IP addresses. One of the most crucial foundations of the Internet as we know it today, the Domain Name System, plays a significant part in facilitating our ability to use it conveniently. Additionally, because DNS’s primary function is to link domain names and IP addresses rather than to provide security, it is vulnerable to several cyber threats like DDoS attacks. As a result, implementing additional features like DNSSEC, DDoS Protected DNS, DNS Failover, DNS Monitoring, etc., is frequently necessary.

Domain name 

The exclusive address for a website is its domain name. This is the address at which Internet visitors can access your website. To identify and map websites and other Internet Protocol (IP) resources, the Domain Name System (DNS) uses host names or domain names. On the Internet, machines are located and identified using their domain names. They are unique and cannot be used by another website. For example, think about internet-eireann.ie

TLD

A TLD is a domain extension that refers to the letters of a domain name that come after the dot. In our example internet-eireann.ie this is .ie. Other popular examples of a TLD include, .com, .net, .org., .gov, .edu, etc. Additionally, there are other TLD types, including:

  • gTLD – It stands for Generic Top-level Domains and popular examples are .org, .com. and .net
  • sTLD – It abbreviation stands for Sponsored Top-level Domains. And the most usable sTLD’s are .edu and .gov.
  • ccTLD – It means Country Code Top-level Domains and the most common among them are: .fr, .uk, .usa, .ie, etc.

TLDs are an essential part of a company’s URL. With them, you may develop client loyalty and target a particular audience.

Conclusion

Congratulations! You are one step closer to the fundamentals of the Internet. You now know all the necessary Internet terms. Additionally, you will now be more aware of what the various components signify when you browse the Internet!
