- 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 the network
administrator. It takes the form as ***.***.***.***, for example,
255.255.255.255.
This item allows users to enter the value of the Netmask for the DVR.
Please note that to configure this item, DHCP must be set to <Off>.
- Gateway
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 DVR. To configure this item, DHCP must be
set to <Off>.
- DNS
DNS is the abbreviation for “Domain Name Server”, which is an Internet
service that translates domain names into IP addresses. The advantage
of using DNS is that domain names are easier to remember.
This item allows users to specify the IP address of the Domain Name
System associated with the DVR. To configure this item, DHCP must be
set to <Off>.
If the server is unavailable when using DHCP, the DVR will search for the
network server and boots up more slowly. This network search continues
until it times out.
- PPPoE Account
The item allows users to setup the PPPoE login username.
NOTE: For accessing the PPPoE settings, select <PPPoE> as the
Network Type in Network Setup menu.
