VPort 2141 Video Encoder User’s Manual
System Configuration
4-8
Two tools are available for administrators to link conveniently to the VPort 2141. The first tool is
DDNS (Dynamic Domain Name System), a combination of DHCP, DNS, and client registration,
all working together. DDNS allows administrators to alias the VPort’s dynamic IP address to a
static hostname in any of the domains provided by the DDNS service providers listed on the
VPort’s DDNS& UPnP configuration page. The VPort will be easier to access from various
locations on the Internet. The second tool is UPnP (Universal Plug & Play), a networking
architecture that provides compatibility between different types of networking equipment,
software, and peripherals of the 400+ vendors that are part of the Universal Plug and Play Forum.
This means that they are listed in the network devices table for the operating system (such as
Windows XP) supported by this function. Users can link to the VPort directly by clicking the
VPort listed in the network devices table.
Dynamic DNS
To enable the DDNS function, the administrator should first apply for a Hostname from the DDNS
service providers’ website. There are 5 providers listed in the VPort: DynDNS.org, TZO.com,
dhs.org, safe100.net, and dyn-interfree.it. Refer to the providers’ rules when enabling the function.

box, and then click save to enable the UPnP function. Users
will be able to find and connect to the VPort directly from the operating system’s network device.
If the UPnP network component is installed in Windows XP, the hostname of the VPort will be
shown with bracketed IP address in the Network neighbors, e.g., VPort 2141 (xxx.xxx.xxx.96). In
other words, the hostname of the VPort is “VPort 2141,” and the IP address of the video encoder is
xxx.xxx.xxx.96, which depends on the last value of the IP address assigned to the video encoder.
