the remaining bits correspond to the host ID.
For example, if the IP address for a device is, in its binary form,
11011001.10110000.10010000.00000111, and if its network mask is,
11111111.11111111.11110000.00000000
It means the device’s network address is
11011001.10110000.10010000.00000000, 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.
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
FTP TCP 21
SMTP TCP 25
POP3 TCP 110
H.323 TCP 1720
