First off, Dynamic DNS, also known as DDNS, is a service that will instantly update your IP address (the A or AAAA record) if the host (device) changes it.
When your IP address’s lease ends, your ISP (Internet service provider) can change it automatically.
You can use DDNS to ensure that the device will remain accessible if you utilize it as a server. Otherwise, you won’t be able to reach the new IP address or determine it from a distance.
Without Dynamic DNS, if you are operating a monitoring server with a camera at home and you have been viewing the video from a distance, the connection will break the instant the ISP changes the IP address, and you won’t be able to see anything.
It offers several highly practical advantages:
Here are some top-notch suppliers if you already think Dynamic DNS is the answer you need.

Having 34 DNS locations worldwide, ClouDNS is simple to install on a variety of operating systems and network connections.
It provides a free Dynamic DNS service that many people may find an excellent place to start. However, if your demands are greater, there is a Premium DNS available that is more powerful and starts at $2.95 per month.
No-IP offers both free and premium plans. With only a few DNS records supported and a limit of 3 hostnames that require confirmation every 30 days, the free plan can feel restrictive. The premium plans are a different situation because they offer significantly more features for $24.95 or $29.95 annually. Additionally, they started selling domain names for profit in 2002, and in 2006, they obtained ICANN accreditation as registrars.
Dynamic DNS can presumably help you save time and money. It is a very helpful piece of technology. In some circumstances, it can even be the sole rational solution to a problem. For example, let’s say you want to use the Internet to supply services or connect to and manage a variety of equipment, including CCTV cameras. Look at this!
