4.2.3 DDNS
The PoE+ Managed Injector Hub offers the DDNS (Dynamic Domain Name System) feature, which allows the
hosting of a website, FTP server, or e-mail server with a fixed domain name (named by yourself) and a
dynamic IP address, and then your friends can connect to your server by entering your domain name no
matter what your IP address is. Before using this feature, you need to sign up for DDNS service providers
such as PLANET DDNS (http://www.planetddns.com
) and set up the domain name of your choice.
PLANET DDNS website provides a free DDNS (Dynamic Domain Name Server) service for PLANET devices.
Whether the IP address used on your PLANET device supporting DDNS service is fixed or dynamic, you can
easily connect the devices anywhere on the Internet with a meaningful or easy-to-remember name you gave.
PLANET DDNS provides two types of DDNS services. One is PLANET DDNS and the other is PLANET Easy
DDNS as shown in Figure 4-2-4.
PLANET DDNS
For example, you've just installed a PLANET IP camera with dynamic IP like 210.66.155.93 in the network.
You can name this device as “Mycam1” and register a domain as Mycam1.planetddns.com at PLANET DDNS
(http://www.planetddns.com
). Thus, you don't need to memorize the exact IP address but just the URL link:
Mycam1.planetddns.com.
PLANET Easy DDNS
PLANET Easy DDNS is an easy way to help user to get your Domain Name with just one click. You can just
log in to the Web Management Interface of your devices, say, your PoE+ Managed Injector Hub, and check
the DDNS menu and just enable it. You don’t need to go to http://www.planetddns.com
to apply for a new
account. Once you enabled the Easy DDNS, your
PLANET Network Device will use the format PLxxxxxx where xxxxxx is the last 6 characters of your MAC
address that can be found on the Web page or bottom label of the device. (For example, if the PoE+ Managed
Injector Hub’s MAC address is A8-F7-E0-81-96-C9, it will be converted into pt8196c9.planetddns.com)
