Operation Manual

When both are represented side by side in their binary forms, all bits in the IP address that
correspond to 1’s in the network mask become part of the IP network address, and the
remaining bits correspond to the host ID.
For example, if the IP address for a device is, in its binary form,
11011001.10110000.1001
0000.00000111, and if its network mask is,
11111111.11111111.11110000.00000000
It means the device’s network address is
11011001.10110000.1001
0000.00000000, and its host ID is,
00000000.00000000.00000000.00000111
. This is a convenient and efficient method for
routers to route IP packets to their destination.
ISP Gateway Address: (see ISP for definition). The ISP Gateway Address is an IP address
for the Internet router located at the ISP's office.
ISP: Internet Service Provider. An ISP is a business that provides connectivity to the Internet
for individuals and other businesses or organizations.
LAN: Local Area Network. A LAN is a group of computers and devices connected together in
a relatively small area (such as a house or an office). Your home network is considered a LAN.
MAC Address: MAC stands for Media Access Control. A MAC address is the hardware address
of a device connected to a network. The MAC address is a unique identifier for a device with
an Ethernet interface. It is comprised of two parts: 3 bytes of data that corresponds to the
Manufacturer ID (unique for each manufacturer), plus 3 bytes that are often used as the
product’s serial number.
NAT: Network Address Translation. This process allows all of the computers on your home
network to use one IP address. Using the broadband router’s NAT capability, you can access
the Internet from any computer on your home network without having to purchase more IP
addresses from your ISP.
Port: Network Clients (LAN PC) uses port numbers to distinguish one network
application/protocol over another. Below is a list of common applications and protocol/port
numbers:
Application Protocol Port Number
Telnet TCP 23
