“aaa” can be anything from 000 to 255, or as four cascaded binary numbers
separated by “.”: bbbbbbbb.bbbbbbbb.bbbbbbbb.bbbbbbbb, where each “b”
can either be 0 or 1.
A network mask is also a 32-bit binary pattern, and consists of consecutive
leading
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,
11011001.10110000.1001
11111111.11111111.11110000.00000000
0000.00000111, and if its network mask is,
It means the device’s network address is
11011001.10110000.1001
00000000.00000000.0000
0000.00000000, and its host ID is,
0000.00000111
ISP Gateway Address:
(see ISP for definition). The ISP Gateway Address is
an IP address for the Internet Smart Repeater located at the ISP's office.
. This is a convenient and efficient
method for Smart Repeaters to route IP packets to their destination.
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.
WLAN:
Wireless
Local Area Network. A WLAN is a group of computers and
devices connected together in a relatively small area (such as a house or an
office) wirelessly. Your wireless home network is considered a WLAN.
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.
