IP Addressing
The concept of a global Internet addressing scheme
is fundamental to IP. Every Internet-connected system has a unique
Internet host address. This is a 32 bit, or 4 byte, binary
number.
Internet addresses are written as a dotted sequence of the form:
aa.bb.cc.dd
where aa, bb, etc, are the decimal values (ranging
from 0 to 255) of the 4 bytes which make up the internet address,
for example:
149.144.21.60
This is called the "Common Internet Address
Notation". Internet addresses are commonly referred to as
"IP addresses".
The dotted sequence 149.144.21.60 is the IP address
of "ironbark", or to use its full domain name,
ironbark.bendigo.latrobe.edu.au.. Note that the
traditional Internet literature refers to internet-connected
computers as hosts, which reflects the historical
nature of computers as multi-user timeshared systems.
