DHCP
This item allows the user to obtain a dynamic IP address from a DHCP
(Dynamic Host Configuration Protocol) server while the unit boots up. When
using DHCP, the settings are dynamic and they will change every time you
power up and power off the unit, depending on your network's setup.
If the DHCP is enabled (ON), a dynamic IP will be assigned to the DVR-4TH/
8TH/ 16TH series unit. In this case, the user does not need to configure a
static IP or the Ethernet settings including IP address, Netmask, Gateway,
and DNS settings will be “read only”. The default setting is <ON>.
If you are using permanent addressing, set DHCP to <OFF> for setting the IP
Address, Netmask, Gateway, and DNS. See your network system
administrator or IT personnel for appropriate values for these setting.
IP
This item is used to configure the IP (Internet Protocol) address of the unit.
The IP address is the identifier for your computer or device on a TCP/IP LAN
or WAN. Please note that to set a static IP address, DHCP must be set to
<OFF>.
Netmask
A netmask is a 32-bit mask used to divide an IP address into subnets and
specify the networks available hosts. Its value is defined by your network
administrator. It takes the form as ***.***.***.***, for example,
255.255.255.255.
This item allows the user to enter the value of the Netmask for the unit.
Please note that to configure the item, DHCP must be set to <OFF>.
Gateway
A Gateway is a node on a network that serves as an entrance to another
network.
Users are allowed to specify the IP address of the gateway or router
associated with this unit. To configure this item, DHCP must be set to <OFF>.
