Network - Basic TCP/IP settings
IP Address Configuration - Your Axis video server supports both IP version 4 and IP version 6. Both versions may be enabled simultaneously; at least one version must 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 video server receives 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 
.
Notes: | • DHCP is a protocol for automatic IP address assignment on a network. IP address |
| assignment via DHCP may cause the IP address to change and you may lose contact with |
| the camera. Configure the options for notification of IP address change (under Services) to |
| receive notification from the camera when the IP address changes. |
| • Alternatively, if your DHCP server can update a DNS server, you can access the video |
| server by host name which is always the same, regardless of the IP address. |
