2.5.2 Setting up DDNS
1. DDNS?
In general, Internet service providers allocate floating IP to subscribers. Therefore, when attempting for connection to
device from the outside, IP address is changed as floating IP. In this case, dynamic domain name service (DDNS)
function is useful. DDNS refers to the service that enables connection with own name rather than floating IP.
MBox supports DDNS function.
However, this function must be used in conjunction with the previously mentioned DMZ or port forwarding function, if IP
address of IP Sharing Router is floating IP. When connection is made with domain name without setting DMZ or port
forwarding, connection is made only to IP Sharing router, not MBox.
2. Configuring DDNS
• Type in the name you want to register and press SET.
• The name should be composed of a combination of alphanumeric letters. You can't use numeric letters alone. The
maximum length allowed is twelve letters.
• Even if this convention is satisfied, you can't register a name already taken by another user.
• When the registration is successful, you can access with the registered name from the outside.
3. Deleting DDNS
• Press DELETE to delete a registered name.
• You can registered a new name after deleting the old one.
