Figure 3.4: Building of the IP address<br />
Classes of IP addresses<br />
IP addresses are divided in<strong>to</strong> different classes. Figure 3.5 shows an overview.<br />
Figure 3.5: The different classes within IP addressing<br />
Table 3.1 shows the features of class A, B and C. Class D is added in order <strong>to</strong> send multicast<br />
messages in a simple way. Class E currently has no function yet.<br />
The distinction between the classes A, B and C is determined by the number of bytes that<br />
are part of the Net ID on the one hand and the number of bytes that are part of the Host ID<br />
on the other hand. The largest number of bits in the IP address determine <strong>to</strong> which class an<br />
IP address will belong. Table 3.1 sums up all features of the three different classes.
