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 listed below for explanations). 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 as 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
comprises two parts: 3 bytes of data that corresponds to the
Manufacturer ID (which is 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 identify one
network application/protocol from another. Below is a list of common
applications and protocol/port numbers:
Application Protocol Port Number
Telnet TCP 23
