About DDNS services (IPv4/IPv6)
By using a DDNS service, it becomes possible to view camera images via the Internet.
The DDNS service associates dynamic global addresses and domain names.
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 (http://www.viewnetcam.com/) 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).
