How to Create and Configure Dynamic DNS DDNS with DYN and Access Home

The public IPs that our Internet connections have can be static or dynamic. On the one hand, fixed or static public IP addresses are those that are always the same, even if you turn off the router and regardless of the time that passes. On the other hand, dynamic IPs are the ones that change every so often and the ones that the vast majority of home users have. In this tutorial we are going to explain what a dynamic DNS is , and how to create a host with DYN to access your home computer from abroad knowing the domain of the DYN host.

In case you don’t know, having a fixed public IP requires an extra payment on the Internet connection bill. Generally, a home user will not need a static IP, they are more used by companies. However, on some specific occasions, we may need to connect from the Internet to our home because we have a server of some kind. Then a dynamic DNS (DDNS) with DYN can be the solution to our problems.

Create and Configure Dynamic DNS DDNS with DYN

What is DDNS or Dynamic DNS

The acronym DDNS comes from the English Dynamic Domain Name System , or translated into Spanish, Dynamic Domain Name System . Its main function is that it helps when forwarding the public IP addresses of our home network to a specific domain that we can configure.

As we have already mentioned previously, it is very common in our homes to have dynamic public IPs that change from time to time. The advantage that using a dynamic DNS offers us is that we can access our PC, FTP server, VPN server, game server and web server from home, with an easy to remember domain. Thus, we can avoid the need to memorize a lot of public IPs, which, moreover, change from time to time. In this sense, keep in mind that dynamic IP addresses can change several times a month. It should also be noted that memorizing words is usually easier than learning random numbers. Also, in the event that we have a dynamic IP and it changes, nothing happens, in this case it will automatically re-synchronize with the host in DYN and we will have no problems. The only condition for this to happen is that you configure the router correctly.

Redes DDNS

A solution of this type would be to contract a dynamic DNS with DYN. In order to use this service, the first thing we would have to do is create an account for this DDNS service, and then create a free Host name . From that moment, after having also configured it on the router, we can always know the public IP address. Thus, even if we do not know what our current public IP is, our dynamic DNS service will take care of updating the public IP as soon as it changes.

Is it profitable to hire a dynamic DNS payment service like DYN?

In the case of wanting a reliable and effective solution so that you can always access your servers, you have two options:

  • Hire a static public IP from your Internet provider or ISP.
  • Pay to use a dynamic DNS service.

Regarding hiring a public IP, with our ISP it supposes an additional cost of between € 10 or € 15 more per month on the Internet bill. This, throughout the year, translates into an expense of between € 120 and € 180 depending on the Internet provider we have.

Then we would have the option of using a free or paid dynamic DNS. The advantage of the free one is that it is at zero cost, the disadvantage it has is that it comes with certain limitations. Among the most common would be:

  1. The limit on the number of hostnames (DNS domains to create).
  2. The expiration of the Hostname, if you do not use it in a month or renew it from time to time, this hostname is automatically deactivated.

In summary, with the free ones you have to be aware so that they do not lose validity. On the other hand, we have a dynamic DNS with DYN for $ 55 and not be worried about it expiring. In this sense, it should also be noted that it represents a saving of close to 50% or more compared to hiring a static IP with an operator.

How to create an account at DYN

If we want to use Dynamic DNS with DYN, the first thing we have to do is register on its official website . In this sense, it should be noted that Oracle has been the owner of this service since 2016. This is a screenshot of the DYN website:

The first thing we are going to do is click on the Try Dynamics DNS button . If you click on the Buy Dynamics DNS button you can check the prices. I remind you that the annual price is € 55, you can try the service for a week for free, but it is required that you fill in your details and put a credit card.

Next, we will proceed to create the account:

Here we have to fill in:

  • Username : which will be our username.
  • Password and Confirm password : to establish our password.
  • Email and Confirm Email : the email where the confirmation code comes from.

Next, we solve the CAPTCHA, accept the Oracle conditions and click on Create Account . Then a screen like this will appear, which asks us to enter the confirmation code.

The next step we will take is to go to the email that we have provided to create a dynamic DNS with DYN.

The next step that we are going to take is to put that password and click on the Confirm button. One thing to keep in mind is that sooner or later, we will have to fill in our personal information and put in a credit card to enjoy the 7-day trial.

Create dynamic DNS hostname

Once we have logged into our DYN account, a screen like this will appear:

If this screen does not appear, you can find it in Services , Services overview . Now it is time to create the Host for which we will click on Add Hostname . Then these options will appear to configure the Host:

The first thing we are going to do is choose the name of our Host and then on the right we choose the ending that we like the most. In the second, we select Host with IP address and click on the red box to assign our current IP.

Once this is done we save the changes and we only have to configure the hostname in the router.

DYN hostname configuration on a router

Here we have to start by entering the configuration of our router through the web. We will do it in our browser by putting the gateway and then your username and password. If we want to configure a dynamic DNS with DYN we will have to look for its corresponding section. It is usually called by one of these names or similar:

  • DynDNS
  • DDNS
  • Dynamic DNS

This time, we are going to use an AVM FRITZ! Box 7530. We will go to the Internet , Allow access and then we will go to DynDNS .

Next, we will start by activating the Use DynDNS box.

Then you have to configure these sections:

  • DynDNS provider : we have to search and select dyndns.org. In registering a new domain name, you will see how it directs you to the DYN website and if you enter your username and password you can access the account.
  • Domain name: the name of the hostname we created, in this case redeszonepruebas.dyndns-pics.com.
  • Username : we put the username of our DYN account.
  • Password : we write the password of our DYN account.

Finally, click on Apply and with that we have finished creating a dynamic DNS with DYN. From this moment on, you will be able to enter your computer from anywhere by putting said HOST as if it were the IP.
