3) Operation
Before you use Quick DDNS, you need to enable this service and set the correct server address, port
value, and domain name.
Server address: www.quickddns.com
Port number: 80
Domain name: There are two modes: Default domain name and customized
domain name.
In addition to default domain name registration, you can also use a customized domain name (You
can input your self-defined domain name.) After successful registration, you can use domain name
to login to access the device.
User name: This is optional. You can input your commonly used email address.
Do not register frequently. The interval between two registrations should be
more than 60 seconds. Too many registration requests may result in a server
attack.
The system may take back the domain name that is idle for one year. You can get
a notification email before the domain is reclaimed if your email address setup is
correct.
