5 classes of ip address pdf
What are the five different classes of IP addresses? IP address → Network Address 1. Find the class, then the Netid, then set Hostid = 0 Example: IP= 134. 2 is a class Bwith Netid= 134. 45, so its network address is 134. Use a Mask which is a 32- bit binary number that gives the first address in the block ( the network address) when bitwise ANDed with an address in the block. The decimal representation is what you can use to identify the class that an IP address belongs to. An IP class is a complete range of IP addresses that are designed to provide an addressing scheme that can accommodate small and large scale networks. Private IP address 172. 255 16 Address range 128. 0 Class C Addresses Class C addresses take the following binary form: 110bbbbb. bbbbbbbb The leading three digits, or high- order bits, are 110, and the remaining digits ( marked with a b) can be either 1s or 0s. Note that this scheme reduces the.
How many classes are there in IP addressing? Internet Protocol hierarchy contains several classes of IP Addresses to be used efficiently in various situations as per the requirement of hosts per network. Broadly, the IPv4 Addressing system is divided into five classes of IP Addresses. All the five classes are identified by the first octet of IP Address. addresses, it represents 12. 5% ( or 1/ 8th) of the total IPv4 unicast address space. Other Classes In addition to the three most popular classes, there are two additional classes. Class D addresses have their leading four- bits set toand are used to support IP Multicasting. Class E addresses have their leading four- bits set toand are. Class A, for example, 10. For large networks with many devices. Zachary Craft answered IP addresses are divided into classes so that they can be assigned to a particular business, government or other entity based on size and need. There are five IP classes plus certain special addresses:. Why are IP addresses divided into classes? IP Address Classifications Class Bits in Network ID Number of Networks Bits in Host ID Number of Hosts/ Network Address Range Subnet Mask A, 000, 000 1.
How can we identify the class of the IP address? With an IPv4 IP address, there are five classes of available IP ranges: Class A, Class B, Class C, Class D and Class E, while only A, B, and C are commonly used. Class D IP Address Class D IP addresses were reserved for multicasting purposes. These addresses begin with an octet in therange. They would have leading bits ofand includes addresses from 224. Class E IP Address Class E IP addresses are reserved for experimental use. The first octet of these
