1’s follo w ed b y co nsecutive trailing 0’s, such as

11111111.11111111.11111111.00000000. Therefore sometimes a network

mask can also be de scribed sim p ly as “x” num be r of leadin g 1 ’s.

When both are represented side by side in their binary forms, all bits in the

IP add ress that corresp ond to 1’s in the netw ork m ask b ecom e 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 m ea ns the device’s netw ork a ddress 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 u sed as the product’s se rial num ber.

NAT: Network Address Translation. This process allows all of the

computers on your home network to use one IP address. Using the

bro adba nd rou ter’s N A T capa bility, yo u can access the In ternet from a n y

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:
