The term address classes appears in Linux, MAC-OS as well as under MS Windows OS and here is the explanation!These are predefined groupings of Internet addresses, in which each class describes networks of a certain size. The number range permitted for the first octet in the IP address depends on the address class. Class A networks (values 1 to 126) represent the largest networks with more than 16 million hosts per network. In class B networks (128 to 191) there are up to 65,534 hosts, in class C networks (192 to 223 ) there can be up to 254 hosts per network. Class A IP address Are IP addresses between 1.0.0.1 and 126.255.255.254. The first octet indicates the network and the last three octets refer to the host on the network. Class B IP address An IP address between 128.0.0.1 and 191.255.255.254. The first two octets indicate the network, and the last two octets refer to the host on the network. Class C IP addresses are between 192.0.0.1 and 223.255.255.254. The first three octets indicate the network, and the last octet refers to the host on the network. Network load balancing provides optional session support for Class C IP addresses (in addition to supporting single IP addresses) to allow multiple proxy servers to be used on the client side. PS: Is also awarded by the FritzBox and SpeedPort ! Class D IP address Use for multicast applications 224.0.0.0 - 239.255.255.255
IP address of class E 240.0.0.0 - 255.255.255.255 reserved (for future use)
►► ... How can I find out my IP addresses (PC name)?Info:
The system of IP address classes was developed for the purpose of assigning Internet IP addresses. The classes created were based on the network size. For example, class A was created for the small number of networks with a very large number of hosts. Class C was created for numerous networks with a small number of hosts.
