Dynamic DNS explained
The Dynamic DNS (DDNS) automatically updates and changes the IP address of a host. Thanks to it, visitors are able to reach your website even in case its IP address changes.
As a very simple service, Dynamic DNS gives you the opportunity to connect with your various hosted services when the ISP changes your IP address (IPv4 or IPv6). Let’s say, for instance, you could have a web hosting server, database server, mail server, or maybe you utilize your home network for your CCTV cameras together with DDNS.
