4. 32 bit address structure The address is usually written in dot notation also called dotted decimal notation in which each group of eight bits is written in decimal form separated by decimal points For example the following binary address 11000011 00100010 00001100 00000111 is normally written as 195 34 12 7 The latter version is easier to remember and easier to enter into your computer In addition the 32 bits of the address are subdivided into two parts The first part of the address identifies the network and the second part identifies the host node or station on the network The dividing point may vary depending on the address range and the application There are five standard classes of IP addresses These address classes have different ways of determining the network and host sections of the address allowing for different numbers of hosts on a network Each address type begins with a unique bit pattern which is used by the TCP IP software to identify the address class After the address class has been determined the software can correctly identify the host section of the address The follow figure shows the three main address classes including network and host sections of the address for each address type Understanding IP Addresses B 1 User Manual for the NETGEAR PS121 Mini Print Server Class A Network Node Class B Network Node Class C Network
