1’s followed by consecutive trailing 0’s, such as
11111111.11111111.11111111.00000000. Therefore sometimes a
network mask can also 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
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.
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:
