An address includes both a network number and a host number. The
actual format of these numbers varies depending on the class of
address being designated. Address class is determined by the value
in the first octet of the address.
Table 6-4 shows valid address classes, the range of the first address
field, and the resulting address format. The maximum value for any
single field is 255.
