Netmask; Gateway - Speco DVR-4TN User Manual

User's Manual
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.
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>.
DNS
DNS is the abbreviation for "Domain Name System", which is an Internet
service that translates domain names into IP addresses because domain
names are easier to remember.
This item allows the user to specify the IP address of the Domain Name
System associated with the unit. To configure this item, DHCP must be set to
<OFF>.
If the network server is unavailable when using DHCP, the unit searches for
the network server and boots up more slowly. This network search continues
until it times out.
