2) Network
The VK2-VGAVFD support 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 for
the video encoder can be set automatically via DHCP, or a static IP address can be set manually.
If IPv6 is enabled, the video encoders receive an IP address according to the configuration in the
network router. There is also the option of using the Internet Dynamic DNS Service. For more
information on setting the Network, please see Setup> System>Security>Network.
• Obtain IP address via DHCP - Dynamic Host Configuration Protocol (DHCP) is a protocol
that lets network administrators centrally manage and automate the assignment of IP
addresses on a network. DHCP is enabled by default. Although a DHCP server is mostly
used to set an IP address dynamically, it is also possible to use it to set a static, known IP
address for a particular MAC address.
• Use the following IP address - To use a static IP address for the VK2-VGAVFD,
check the radio button and then make the following settings:
- IP address: Specify a unique IP address for your VK2-VGAVFD.
- Subnet mask: Specify the mask for the subnet the VK2-VGAVFD is located on.
- Default router: Specify the IP address of the default router (gateway) used for
connecting devices attached to different networks and network segments.
Notes:
1. DHCP should only be enabled if using dynamic IP address notification, or if your DHCP server can
update a DNS server, which then allows you to access the VK2-VGAVFD by name (host name). If
DHCP is enabled and you cannot access the unit, you may have to reset it to the factory default
settings and then perform the installation again.
