consecutive leading 1’s followed by consecutive trailing 0’s, such as
11111111.11111111.11111111.00000000. Therefore, a network mask
can sometimes be described simply as “x” number of leading 1’s.
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, 11011001.10110000.10010000.00000111, and
if its network mask is 11111111.11111111.11110000.00000000, then
its 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.
isp gateway address:
This is an IP address for the Internet router
located at the ISP’s office.
isp:
An Internet Service Provider is a business that provides connectivity
to the Internet for individuals, businesses or organizations.
lan:
A local Area Network is a group of computers and devices
connected together in a relatively small area,such as a house or
office. Your home network is considered a LAN.
Mac address:
A Media Access Control 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’s composed
of two parts: 3 bytes of data corresponding to the manufacturer Id
(unique for each manufacturer), plus 3 bytes often used as the
product’s serial number.
nat:
Network Address Translation is a process that allows all of the
computers on your home network to use one IP address. Using the
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 from another. Below is a list of common
applications and protocol/port numbers:
