The standard DNS uses A or AAAA DNS entries to connect domain names to IP addresses. Dynamic DNS can automatically update and change the host’s IP address. The users can access it even if their IP address changes.

An easy service to use is Dynamic DNS. When your ISP changes your IP address, it is simple for you to access your hosted services. You may utilize your home network for CCTV cameras with DDNS, for instance, or you could have a web hosting server, mail server, database server, etc.
