Ddns Server - Planet ICA-530 User Manual

Secondary DNS: The same function as DNS1. It is option not necessary
Note: need to reboot the device to take this setting effect.
HTTP Port: The device supports two HTTP ports. The first one is default port 80 and this port
is fixed. This port is very useful for Intranet usage. The second HTTP port is changeable.
Users could assign the second port number of http protocol, and the WAN users should follow
the port number to login. If the http port is not assigned as 80, users have to add the port
number in back of IP address. For example: http://192.168.0.20:80.
If multiple devices are installed on the LAN and also required to be accessed from the WAN,
then the HTTP Port can be assigned as the virtual server port mapping to support multiple
devices.
Video Port: Specify the transmission port number of video stream. The default value is 5000.
User can specify a number between 1024 and 65535.
When the configuration is finish, please click "OK" to save and enable the setting.

3.5.2 DDNS server

DDNS: Stands for Dynamic Domain Name Server
The device supports DDNS. If your device is connected to xDSL directly, you might need this
feature. However, if your device is behind a NAT router, you will not need to enable this feature.
Because DDNS allows the device to use an easier way to remember naming format rather
than an IP address. The name of the domain is like the name of a person, and the IP address
is like his phone number. On the Internet we have IP numbers for each host (computer, server,
router, and so on), and we replace these IP numbers to easy remember names, which are
organized into the domain name. As to xDSL environment, most of the users will use dynamic
IP addresses. If users want to set up a web or a FTP server, then the Dynamic Domain Name
Server is necessary. For more DDNS configuration, please consult your dealer.
Your Internet Service Provider (ISP) provides you at least one IP address which you use to
connect to the Internet. The address you get may be static, meaning it never changes, or
dynamic, meaning it's likely to change periodically. Just how often it changes, depends on your
ISP. A dynamic IP address complicates remote access since you may not know what your
current WAN IP address is when you want to access your network over the Internet. The
solution to the dynamic IP address problem comes in the form of a dynamic DNS service.
The Internet uses DNS servers to lookup domain names and translates them into IP
addresses. Domain names are just easy to remember aliases for IP addresses. A dynamic
DNS service is unique because it provides a means of updating your IP address so that your
listing will remain current when your IP address changes. There are several excellent DDNS
services available on the Internet and best of all they're free to use. One such service you can
use is www.DynDNS.org. You'll need to register with the service and set up the domain name
of your choice to begin using it. Please refer to the home page of the service for detailed
instructions or refer to Appendix D for more information.
