Common Types Of My IP Address Classes 1961

Initially, the ability of my IP addresses was determined by classes that they were organized into. As such, the bits that were used to identify the exact network that a device was operating in were determined by the specific class that an address was classified into. This could furthermore help to identify the network identity and that of host computer in addition to defining the number of hosts subnets there were in a single network. This article therefore looks at the most common classes of my IP address classes that you can put into consideration when out looking for an appropriate address.

•    Class A- these are designed for networks with a large number of hosts. This is because it can allow up to 126 networks with the initial octet of the bit being set at zero. The next seven octets are set to one which makes up the network ID. The remaining octets represent the hosts ID allowing for 17 million hosts in a single network. This class has numbers value beginning at 1 and ending with 127.
•    Class B- this class of addresses is suitable for both medium and large networks. It allows for 16, 384 networks through using the first two octets for the network ID. The first two bits are normally fixed to 10 and the remaining 6 completing the network ID. The other 16bits in the third and fourth octets represent the host ID and allows up to 65, 000 hosts per network. The number values in this class begin at 128 and end at 191.
•    Class C- this class of my IP address is used for small local area networks and allows for approximately 2 million networks through using the first three octets for the network ID. Three bits are set to 110 and in the first three octets, the network ID is completed by 21 bits while the host ID is represented by 8 bits of the last octet allowing for 254 hosts per network. Its number values begin at 192 and end with 223. 
•    Class D and E- these ones are very special classes of my IP address because they are not allocated to any host. Class D is used for multi-casting while class E is reserved for future purposes only and not general use.

Generally, the four octets that make up an IP address are mostly represented by a, b, c and d in that order. They are however distributed randomly among the classes thus be keen when choosing one to avoid going for the wrong one.
