Switch Management and Operating Concepts
In a subnetted network, all addresses consist of two parts: an IP
address and a subnet mask. The two are used together and one is
meaningless without the other.
IP Addresses
The Internet Protocol (IP) was originally designed to allow
communication across network sites comprising the Internet. It
was later adapted to allow routing between subnets within a site
(within an intranet). The IP includes a system by which an unique
number is assigned to each network and to each computer within
each network. This number is called the IP address.
IP addresses are written in a ‘dotted decimal’ notation to make
them easier to work with. Some examples follow:
1. 210.202.204.205
2. 189.21.241.56
3. 125.87.0.1
The four decimal (base 10) values in an IP address represent four
eight bit binary (base 2) numbers. A computer can only interpret
the binary numbers. The dots are simply visual separators, a
computer interprets an IP address as a series of 32 binary digits
(as a 32 bit number).
The same three IP address, from above, are written below in binary
form. The dots are retained for clarity.
