Operating Instructions 2.8.1 DynamicDNS Service (IPv4/IPv6) DynamicDNS allows you to choose an easy-to-remember address (such as "bob.viewnetcam.com") that can be used to view images from your camera over the Internet. This service is compatible with both IPv4 and IPv6 addresses. Some DynamicDNS service is not compatible with IPv6 address. What are the advantages of DynamicDNS service? In order to view camera images over the Internet, you need to know your camera's global IP address. However, many Internet Service Providers (ISPs) assign their customers a "dynamic" IP address that changes monthly, weekly, or each time they log on. Unless you have been assigned a static IP address (an IP address that does not change periodically) by your ISP, you may find it difficult to access your camera over the Internet. The Viewnetcam.com service allows you to access your camera even if your assigned global IP address changes. How the DynamicDNS service works DynamicDNS service server DNS server 3. New address registered with DNS server 4. DNS looks up current address Internet 2. Camera reports new address On-site Network ISP Camera 1. Global IP address changes Off-site PC 5. Camera connection established 1. Your ISP assigns a global IP address to your Internet access account that changes periodically. This is the address needed to access the camera over the Internet. 2. When your ISP-assigned global IP address changes, your camera automatically notifies the DynamicDNS service server of the new address in the DynamicDNS. The camera notifies the DynamicDNS service server of the new address in DynamicDNS in the following cases. • When starting the camera • When an update interval time has been set • When clicking the [Save] button 3. The DynamicDNS server contacts the Domain Name System (DNS) server and registers your new global IP address to your chosen DynamicDNS address (such as "bob.viewnetcam.com"). 65
