IP Address Configuration
Your Axis network camera supports both IP version 4 and IP version 6. Both versions may be enabled simultaneously, and at least one version must always be enabled.
When using IPv4, the IP address can be set automatically via DHCP, or a static IP address can be set manually.
If IPv6 is enabled, your camera will receive an IP address according to the configuration in the network router.
There are also options for setting up notification of changes in the IP address, and for using the AXIS Internet Dynamic DNS Service. For more information on setting the IP address, please see the online help.
