DDNS Wi-Fi equipment

DDNS

— the device supports the DDNS function – assigning a permanent domain name to a device with a changing (dynamic) IP address.

For network electronics, the IP address is of key importance, it allows the equipment to send data packages to the right device. However, such addresses are sequences of numbers that are poorly remembered by people. Therefore, domain names appeared – on the Internet these are web addresses (for example, ek.ua), on the local network – the names of individual devices (for example, "Work laptop" or "Sergey's Computer"). Both on the Internet and in local networks, so-called DNS servers are responsible for the communication between a domain name and an IP address: for each domain in the database of such a server, its own IP is registered. However, for technical reasons, situations often arise when the router has to use a dynamic (changeable) IP; accordingly, in order for information to be constantly available on the same domain name, it is necessary to update the data on the DNS server with each IP change. It is this update that the DDNS function provides.
