The DDNS nomenclature refers to the Dynamic Domain Name System , or translated, Dynamic Domain Name System . Its usefulness lies in the fact that it helps when forwarding the public IP addresses of your home network to a specific domain that we can configure. We must remember that the public IPs that we usually have in the connections, constantly change as they are generally dynamic, and instead, we would use a fixed domain name.Ī free example that we can use of dynamic DNS is No-IP, a service that is free, although with certain limitations, since we also have a more complete paid version. In order to use this service, all we have to do is register for this DDNS service, and then create a free Host name. ![]() The advantage of using a dynamic DNS is that we can access our computer, FTP server, VPN server, game server and WEB server with an address that is easy to remember. We are going to avoid the need to memorize public IPs, if we take into account that most are dynamic IP addresses, there will be a few over a month. Regardless of this, memorizing words is usually easier than learning random numbers. Also, if you have a dynamic IP, nothing happens, as it will automatically re-sync and work without problems. The only condition for this to happen is that you configure the router correctly or have the No-IP client installed on your PC. Normally it is always configured in the router so that as soon as the IP changes, it updates the IP address automatically, in addition, What is DDNS or Dynamic DNS The public IPs offered by Internet providers or ISPs can be of two types. Fixed public IP addresses are the ones that are always the same, regardless of whether a certain time passes or you turn off the router, and they usually need an extra cost on the bill. Dynamic IPs, on the other hand, are those that change from time to time and those that the vast majority of home users have, are the ones that normally come included with the Internet connection. In this tutorial we are going to explain what a dynamic DNS is, and how to create a host with No-IP to access your home computer from outside knowing the domain of the No-IP host.
