1) Classful Addressing IPv4 addressingused the concept of classes. This architecture is known asclassful addressing. In the classful addressing, there are 5 classes in which the address space is divided:A, B, C, D, and E. Each class occupies some fraction of the address space. ...
The earlier implementation of IPv4 usedaddress classesto divide the address space intonetwork and node components. This arrangement was very wasteful of IP addresses and was discontinued, but the termsClass A, B and Cnetworks are still used. IP4 Address Classes The address classes divide the addre...
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...
IPv4 addresses that do not duplicate already-assigned public addresses are required. To solve this addressing problem, the Internet designers reserved a portion of the IPv4 address space and named this space the private address space. An IPv4 address in the private address space is never assigned...
IPv4 uses hierarchical addressing scheme. An IP address, which is 32-bits in length, is divided into two or three parts as depicted − A single IP address can contain information about the network and its sub-network and ultimately the host. This scheme enables the IP Address to be hierar...
Figure 8-2Five classes of IPv4 addresses Most IP addresses in use belong to Class A, Class B, or Class C. Class D addresses are multicast addresses, and Class E addresses are reserved. The easiest way to determine the class of an IP address is to check the first bits in its network ...
A network can be divided into multiple subnets to conserve IP address space and support flexible IP addressing. When many hosts are distributed on an internal network, the internal host IDs can be divided into multiple subnet IDs to facilitate management. Then the entire network contains multiple ...
Key Differences between IPv4 and IPv6 IPv4 is a 32-Bit IP address, whereas IPv6 is a 128-Bit IP address. IPv4 uses a numeric addressing method, represented in dot-decimal notation (e.g., 192.168.1.1), while IPv6 employs an alphanumeric addressing method in colon-hexadecimal format (e....

If you are using only classful (strict adherence to A, B, and C network address boundaries) IP addresses, the prefixes are the same as the masks for the classes of addresses. For example, using classful IP addressing, a class C IP network address such as 192.168.10....
