Ip Address Classes Pdf 4.2 addressing • the ip address space (all possible ip values) is divided into five classes: a, b, c, d, and e. This document discusses ip address classes and networking concepts. it explains that an ip address is a 32 bit number divided into four octets used to identify devices on a network.
Classes Of Ip Addresses Pdf Ip Address Cisco Certifications 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. Class a ip address class a ip addresses were used for networks that had a large number of ho. ts on the network. the class permitted up to 126 networks by using the first octet of the address for the netw. rk identification. the first bit in this octet was always fixed. Early in the development of ip, the iana (internet assigned numbers authority) designated five classes of ip address: a, b, c, d, and e. these classes were identified based on the pattern of high order bits (the high value bits at the beginning of the first octet). The bootstrap protocol (bootp) operates in a client server environment and only requires a single packet exchange to obtain ip information. bootp packets can include the ip address, as well as the address of a router, the address of a server, and vendor specific information.

E class e addresses are reserved for future use (and class d are usually used for testing only). Table a 1 describes how ip address classes are organized. you can always tell what class an address is by looking at the first octet and comparing it to the chart above. for instance, the address at the top of this appendix has 198 as the first octet, so it is class c. The document explains ip addresses, their classes, and subnetting. it details the two main types of ip addresses, ipv4 and ipv6, and outlines the importance of subnetting for network efficiency and security. Number of bits for class c networks — 24 bit mask = 255.255.255.0, 32 bit mask = 255.255.255.255. the top and bottom host numbers of any subnet may not be used. the bottom number is the subnet address and the top number is the broadcast address for the subnet.
