Ddns Server - Planet ICA-108 User Manual

Primary DNS: When you send email or position a browser to an Internet domain such as
xxxxx.com, the domain name system translates the names into IP addresses. The term refers
to two things: the conventions for naming hosts and the way the names are control across the
Internet.
Secondary DNS: The same function as DNS1. It is option not necessary
Note: need to reboot the device to take this setting effect.
Scan AP: Click the "Scan" button. It will pop up a new window which list is the result of a
network scan. Access points with a disabled SSID Broadcast will not appear unless the
camera is associated with it. The following information is provided:
•
Signal strength - Shows the signal strength.
•
Bit rate - Shows the bit rate in Mbit/s. This can only be shown for the access point
currently in use. Note that the bit rate shown is the current rate, and that this value may
vary over time.
Select "OK" to save and enable the setting.
Note: To enable WLAN function, user must set these related parameters correctly at first.
Then power off the Device and remove Ethernet cable from Device. Power on the Device
again and WLAN mode will be available accordingly.

3.5.3 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 E for more information.
