What is Dynamic DNS?

Dynamic DNS is a DNS service, which provides the option to change the IP address of one or multiple DNS records automatically when the IP address of your device is changed dynamically by the internet provider. The service is also called DDNS or Dyn DNS in technical jargon. If you don’t have a static IP, then the IP changes each time you reconnect to the Internet. To avoid manual update of your records every time the IP changes, you can set up Dynamic DNS for your domain.

This type of service is most commonly used in remote devices (like security cameras, local servers, etc.). Dynamic DNS helps people not to lose access to their devices, regardless of the possible change of their home IP. Why is this happening? The ISPs usually rely on a dynamic allocation of IP addresses to the customers for a certain amount of time. When that time finishes, they will be given a new one.

The pros of Dynamic DNS

If you are considering a static IP address, it is important to remember that there are many different advantages that come with having one. Naturally there are also disadvantages. One of the downsides of configuring a static IP address is that it can grow quite expensive. Free Dynamic DNS by ClouDNS is often regarded as a much more portable option and it will continue to work whether you have a dynamic or static IP address. On the other hand, for all the premium accounts we provide an additional and very beneficial feature - Dynamic DNS history.

Let's see the following situation - you are using services like Amazon EC2 or Google Cloud. By default, they give you a Dynamic IP address. If you want a static IP address, you will be additionally charged. In that case, it's more efficient to have a Dynamic DNS and keep your expenses low.

The way that Dynamic DNS works is by giving a network device the ability to notify DNS servers to automatically change in real time, alongside the active DNS configuration, IP addresses, configured hostnames and some other information. This is something that would normally have to be initiated by the administrator.

Benefits from the Dynamic DNS

Some of the main benefits of setting a Dynamic DNS include:

You can make sure that your system will use the consistent name in the URL you type, even if the IP address for that URL consistently changes.

Efficiency

There is no need to continually change settings on every PC each time you want to change network infrastructure or other options.

Cost savings

You can have many addresses which can all be used at one time rather than the chance of IP address conflict.

Improved Reliability

Enhances the reliability of web services hosted on dynamic IP addresses by ensuring the DNS records are always up-to-date.

Switching to a Dynamic DNS is a fairly easy process and whether you are a business owner or you are interested in working remotely with the help of a VPN, needing remote access for your devices or just hosting your own personal website, it will be helpful to have the advantage of Dynamic DNS on your side.

Consider some of these top advantages and more to switching over to Dynamic DNS and remember that there are plenty of tutorials on our website on how to set up this process and begin.
