Operating Instructions652.8.1 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 overthe Internet. This service is compatible with both IPv4 and IPv6 addresses. SomeDynamicDNS 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'sglobal IP address. However, many Internet Service Providers (ISPs) assign theircustomers a "dynamic" IP address that changes monthly, weekly, or each time theylog on. Unless you have been assigned a static IP address (an IP address thatdoes not change periodically) by your ISP, you may find it difficult to access yourcamera over the Internet. The Viewnetcam.com service allows you to access yourcamera even if your assigned global IP address changes.How the DynamicDNS service works1. Your ISP assigns a global IP address to your Internet access account thatchanges periodically. This is the address needed to access the camera overthe Internet.2. When your ISP-assigned global IP address changes, your cameraautomatically notifies the DynamicDNS service server of the new address inthe DynamicDNS. The camera notifies the DynamicDNS service server of thenew address in DynamicDNS in the following cases.• When starting the camera• When an update interval time has been set• When clicking the [Save] button3. The DynamicDNS server contacts the Domain Name System (DNS) serverand registers your new global IP address to your chosen DynamicDNSaddress (such as "bob.viewnetcam.com").DynamicDNS service serverISPDNSserverInternetNew address registered withDNS serverCamera reports new addressCamera connection establishedGlobal IP addresschangesOff-site PCOn-site NetworkCameraDNS looks upcurrent address3.4.2.1.5.
