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). This is an IP address for the Internet router
located at the ISP's office.
ISP:

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, serving as a unique
identifier for a device with an Ethernet interface. It is composed of two parts: 3
bytes of data that corresponds to the Manufacturer ID (unique for each
manufacturer), plus 3 bytes 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 this 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.

application/protocol over another. Below is a list of common applications and

PPPoE:
Point-to-Point Protocol over Ethernet. This is a secure data-transmission
method originally created for dial-up connections; PPPoE is for Ethernet
connections, and relies on two widely accepted standards: Ethernet and the
Point-to-Point Protocol. It is a communications protocol for transmitting
information over Ethernet between different manufacturers
