Idle Timeout: Idle Timeout is designed so that after there is no traffic to the Internet
for a pre-configured amount of time, the connection will automatically be
disconnected.
IP Address and Network (Subnet) Mask:
IP stands for Internet
Protocol. An IP address consists of a series of four numbers separated
by periods, which identifies a single, unique Internet computer host in
an IP network. Example: 192.168.2.1. It consists of 2 portions: the IP
network address, and the host identifier.
The IP address is a 32-bit binary pattern, which can be represented as four
cascaded decimal numbers separated by “.”: aaa.aaa.aaa.aaa, where each
“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,
11011001.10110000.10010000.00000111, 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.
