IP Address
This address is a unique numbers that identifies a computer or device
on the WAN or LAN. T hese numbers are u sually shown in groups
separated by periods, for example: 192.168.0.200
Subnet Mask
Subnets allow network traffic between hosts to be separated based on
the network's configuration. In IP networking, traffic takes the form of
packets. IP subnets advance network se curity and perf ormance to
some level by organizing hosts into logical g roups. Subnet masks
contain four bytes and usually appear in the sa me "dotted decimal"
data. For e xample, a very comm on subnet ma sk in it s binary
demonstration 11111111 11111111 11111111 00000000 will usually be
shown in the corresponding, more readable form as 255.255.255.0.
Gateway
A gateway is a piece of so ftware or hardware that passes information
between networks. You'll see this term most often when you either log
in to an Inte rnet site or when you're transient email between different
servers.
Obtain DNS from
DHCP
Enable this checked box when a DHCP server is inst alled on the
network and provide DNS service.
Primary DNS
When you send email or position a browser to an Internet domain such
as xxxxx.com, the domain name system translates the names into IP
addresses. The term refers to two things: the conventions for naming
hosts and the way the names are control across the Internet.
Secondary DNS
The same function as DNS1. It is option not necessary
HTTP Port
The device supports two HTTP port s. The first one is default port 80
and this port is fixed. This port is very useful for Intranet usage. The
second HTTP port is changeable. Users could assign the second port
number of ht tp protocol, and the WAN users should follow th e port
number to login. If the http port i s not assigned as 80, users have to
add the po rt number i n back of IP addre ss. For example:
http://192.168.0.20:8080
.
Therefore, the user can access the device by either
http://xx.xx.xx.xx/
, or
http://xx.xx.xx.xx:xxxx/
to access the device.
If multiple de vices are installed on the LAN an d also required to be
accessed from the WAN, then the
HTTP Port
can be assigned as the
