2) Function Introduction
The quick DDNS client has the same function as other DDNS client end. It realizes the
bonding of the domain name and the IP address. Right now, current DDNS server is for
our own devices only. You need to refresh the bonding relationship of the domain and the
IP regularly. There is no user name, password or the ID registration on the server. At the
same time, each device has a default domain name (Generated by MAC address) for your
option. You can also use customized valid domain name (has not registered.).
