What do you need to know about Dynamic DNS?

Dynamic DNS is an amazing service that you can easily implement for your network management, and you can get it for free! So, let’s make things a little bit more clear and explain everything you need to know about it!

What is Dynamic DNS?

Dynamic DNS, or DDNS for short, automatically updates and changes the IP address of a particular host. That makes your website reachable for your clients even in case its IP address changes.

A Dynamic DNS service’s main goal is to allow you to connect with your different hosted services when the ISP (Internet Service Provider) changes your IP address. For example, you could maintain a web hosting, database, or mail server. You can even utilize your home network for your CCTV cameras with Dynamic DNS.

ISPs lease IP addresses only for a specific amount of time, then they change. That is their way of administrating their extensive networks more effortlessly. As an outcome, their clients get a different new IP address when the time expires.

Typically Free Dynamic DNS is the solution, and it helps in many different situations. In addition, it is easy to set up and use. (1)

How does it work?

It is important to choose a reliable DNS hosting provider, like ClouDNS, Dynu, and No-IP, when you want to implement Dynamic DNS.

Once you find the most suitable provider for your needs, you will have to run their software on the host device or router. This precise software notifies the Dynamic DNS service provider when the IP addresses are modified by the ISP. Afterward, the DNS hosting provider adjusts the A record or AAAA record by replacing the old IP address with the new one.

If a particular network is functioning with a static IP address, there is no need to use a Dynamic DNS service. Simply because if a domain name is requested and it holds a static IP address, no additional adaptations are required. Static IP addresses never change. Their main disadvantage, on the other hand, is that they are very pricey.

Advantages of Dynamic DNS

Dynamic DNS service is a great choice when you want to host your website, VPN (Virtual Private Network), access CCTV cameras, or game server on your personal computer. Moreover, it is way more affordable rather than a static IP address. Furthermore, you are not obligated to update manually your DNS records each time your IP address changes.

Let’s talk a little bit more about what advantages Dynamic DNS can provide as well.

Accessibility: Dynamic DNS allows you to effortlessly and rapidly reach the precise website or server. All of your regular activities are not going to be disturbed in case the IP address changes.

Affordability: This is a fact that should not be neglected. It is more than a pleasing factor that you can enjoy your network with fewer expenses. Besides, you should not be concerned about any IP address conflicts even though you have many addresses which you are able to use at the same time.

Practicality: The administrators of your network are not required to reconfigure settings all over again every time an IP address change appears. It relieves them a lot, leaving them with only the more important task of revisiting the network’s health.

There are a lot of other advantages, like the fact that it is really easy to switch to Dynamic DNS, and you can get it absolutely out of charge. (2)

For what is commonly Dynamic DNS used?

Maintaining a server on a network with a dynamic and public IP address requires you to guarantee that users will be able to reach it without any difficulties. That should not be a complicated task! For that reason, exactly Dynamic DNS is going to help you achieve that goal. Besides, you can use this amazing service for:

Personal server. Spending a lot of your finances on a static IP address for your home or office server is unnecessary. You just have to trust Dynamic DNS! It is the perfect solution if your wish is to host a server application, such as an email server, web hosting, storage, and so on.

Surveillance system. That is another great and popular implementation of Dynamic DNS, where it serves flawlessly. You just have to set and install the CCTV cameras, sensors, and other alarm components that you desire. After that, once you implement DDNS, they are going to operate without any disturbance, even if the IP address changes.
