The 6 best free Dynamic DNS providers


A Dynamic DNS service can help you connect remotely to your computer without having to know your IP.

dynamic dns

Every computer and hardware that "goes" on the Internet automatically acquires an IP (Internet Protocol) address, which is a unique number that identifies and identifies you.

This IP is automatically given to you by your internet provider, such as Cosmote, Vodafone, Wind, etc. The simple connections with the above providers, which most users have, are not offered with a static IP (static IP), but it is constantly changing (dynamic IP), according to the needs of your provider. Besides, the static IP costs 10,00 euros per month more, and depending on the pricing policy of your provider.

What is dynamic IP?
The IP is a unique number, style 999.999.999.999, where instead of 9 you will find any number from 0 to 9.

Your IP is unique for everyone at all times, no matter how many changes your provider makes to you. That is, at the same time it is impossible for two different users to connect to the internet with the same IP.

IP, DDNS, dynamic, DNS

The IP address that is constantly changing is called dynamic IP. These changes can be made from every minute up to once a month. When Forthnet was first launched (now Nova) it changed its IP almost once every three to four months.

So if you are not at home and want to connect to it online, you need to know the IP address you have at the moment, which determines your home connection to the internet.

What is your IP now?
If you want to know the IP you currently have, all you have to do is log in on this site. You will see it in blue letters at the top of the page.

Your IP is not hidden. When you access the internet you have a public IP which can be seen by those who visit them and those who visit you. That's why you may have seen intimidating ads like "Your IP is …… and you live in Greece. We know who you are and if you want to protect yourself, get that service etc etc ". Do not be intimidated by such messages.

What is Dynamic DNS?
First of all, the domain is a name, clearly easy to remember, such as "iguru.gr" that someone has matched it with the unique IP that the iguru site has. Instead of remembering the iguru IP which may be 123.456.789.123, it is much easier to remember the name iguru.gr. This correspondence is made by the DNS (Domain Name System) system.

But when this IP changes every now and then then you have to remember a new number every day. Dynamic DNS (DDNS or DynDNS) is a system for mapping domain names to dynamic IP addresses. This allows a web address that has a variable IP address, which is usually "worn" by home users, to always have an easy-to-remember fixed name.

If you want to connect remotely to your computer, then a dynamic DNS is one of the easiest ways to set things up.

Why do I need Dynamic DNS?
Nowadays, remote connection to our computer is very easy. We can connect to see our screen from afar, as if sitting in front of it. Programs like Remote desktop, or Anydesk, or TeamViewer make this job a toy and above all for free. But there are cases that do not cover all our needs, or if they do it is done with many clicks and with delay.

For example, if you want to set up a web server running from your home, or see who is ringing your web bell, or connect your friend to your pc and play a game together, all without putting in your communication with your computer to a third party software manufacturer, but also a lot of other cases, then you should consider connecting via dynamic DNS.

So what are your best free dynamic DNS options? Are they worth using? Here's everything you need to know.

No-IP has always been one one of DynDNS's biggest competitors in free dynamic DNS and when DynDNS went out of business, No-IP was about to take the crown. Unfortunately, in recent years it has slowly shifted towards becoming a premium service.

Free users get three subdomains in a limited selection of domain name options. But these subdomains will never expire, as long as you confirm the activity every 30 days !. To save your computer name, click on the name confirmation link that will be emailed to you seven days before it expires.

No-IP also offers port forwarding and URL forwarding, which can be useful depending on your usage. To keep your computer domain up to date with the latest IP address, No-IP also offers a dynamic update client that monitors any IP changes.
