It is possible to configure the settings for the “Viewnetcam.com” or Dynamic DNS Update (RFC2136 compliant).
In most of the DNS services offered by providers, global addresses are not static but dynamic. Therefore,
access to the camera via an old global address may be invalidated after a certain period of time. Either of the
following services is required when accessing a camera whose global address is not static via the Internet.
•
DDNS service (such as “Viewnetcam.com”)
It is possible to access via a registered and static domain name (example: *****.viewnetcam.com) even
after the global address is changed. Enrollment in a domain name service is required even when using the
IPv6 connection.
Refer to the “Viewnetcam.com” website for further information about the service.
•
Static IP address service (such as a service offered by a contracted provider)
In this service, global addresses are static (not changed).

Global address is changed.
The contracted provider allocates a global address to the router (or the camera). The global address is not
static but dynamic.
“*****.viewnetcam.com” and the current global address is automatically registered.
If you are enrolled in “Viewnetcam.com”, the unique “domain name” (example: *****.viewnetcam.com) will
be allocated. The “Viewnetcam.com” service server automatically manages the domain name of camera
and the global address of router (or camera) when a camera automatically notifies the service server of
the global address.
Current global address is automatically registered via “*****.viewnetcam.com”.
The “Viewnetcam.com” service server registers the global address and the domain name of router (or
camera) in the DNS server.
Global address is obtained via the URL (domain name).
By entering the URL (including the domain name) on the web browser when accessing the camera via the
Internet, the DNS server identifies the registered global address of router (or camera).
