addresses receive the sent messages and alarm snapshots simultaneously.

Dynamic DNS
DDNS (Dynamic Domain Name System) is a combination of DHCP, DNS, and client registration. 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 Network/DDNS configuration page. DDNS makes
it easier to access the VPort from various locations on the Internet.
Setting Description Default
Enable DDNS Enable or disable DDNS function Disable
Provider Select the DDNS service providers, including DynDNS.org
(Dynamic), DynDNS.org (Custom), TZO.com, and dhs.org.
None
Host Name The Host Name you use to link to the VPort. None
Username/ E-mail The Username/E-mail and Password/Key are used to enable
the service from the DDNS service provider (based on the
rules
of DDNS websites).
None
Password/ Key None
NOTE
Dynamic DNS is a very useful tool for accessing a VPort
over the Internet, especially for xDSL connections with
a non
-fixed IP address (DHCP). The administrator and users can simplify connecting to a VPort with a non-
fixed
IP address, by using the unique host name in the URL to establish a connection with the
VPort.
NOTE
Different DDNS service providers have different application rules. Some applications are free of charge, but
most require an application fee.
