Suleyman Demirel University, 2011 EXPLORATION 1 Chapter 6 Addressing the Network – IPv 4 By Zhamanov Azamat
Suleyman Demirel University, 2011 In this chapter, you will learn to: • Explain the structure IP addressing and demonstrate the ability to convert between 8 -bit binary and decimal numbers. • Given an IPv 4 address, classify by type and describe how it is used in the network. • Explain how addresses are assigned to networks by ISPs and within networks by administrators.
Suleyman Demirel University, 2011 In this chapter, you will learn to: • Determine the network portion of the host address and explain the role of the subnet mask in dividing networks. • Given IPv 4 addressing information and design criteria, calculate the appropriate addressing components. • Use common testing utilities to verify and test network connectivity and operational status of the IP protocol stack on a host.
Suleyman Demirel University, 2011 IPv 4 addressing
Suleyman Demirel University, 2012 IP Version 4 • Consists of 32 bits • Divided into 4 octets • Represented in decimal form
Suleyman Demirel University, 2012 Example of IPv 4 3 rd octet 1 st octet 2 nd octet 4 th octet • 192. 168. 1. 21 - > decimal representation • 11000000. 10101000. 000000010101 -> binary representation
Suleyman Demirel University, 2011 From Binary to Decimal

Suleyman Demirel University, 2011 Types of Addressing in IPv 4 Types of Addressing Network Address Host Address Broadcast Address
Suleyman Demirel University, 2011 Network Address • The address by which we refer to the network Network address is same as your Group Name
Suleyman Demirel University, 2011 Network Address
Suleyman Demirel University, 2011 List of Groups • 4 a 03 • 4 b 03 • 4 a 04 • 4 b 04 • 4 c 04
Suleyman Demirel University, 2011 Host Address • Defines host in the network Host address is same like name of group member
Suleyman Demirel University, 2011 Host Address
Suleyman Demirel University, 2011 List of group 4 a 03 • 4 a 03 - Aytekov Danur • 4 a 03 - Abzhanov Nurbek • 4 a 03 - Alahunova Kaminur • 4 a 03 - Arzmetov Zarif • 4 a 03 - Ahet Abilhayir • 4 a 03 - Ahinbekova Akerke • 4 a 03 - Mukashev Serik • 4 a 03 - Muhammed Bagdji Group Name Group Member Name
Suleyman Demirel University, 2011 Broadcast Address • A special address used to send data to all hosts in the network Example of Broadcast in group: 4 a 03 -All
Suleyman Demirel University, 2011 Broadcast Address
Suleyman Demirel University, 2011 Prefix and Subnet Mask • Prefix defines number of bits which belong to Network Address • Subnet Mask defines Prefix
Suleyman Demirel University, 2012 Example of IPv 4 Prefix, identifies that Network Address consists of 24 bits starting from the left side. • 192. 168. 1. 21/24 • 11000000. 10101000. 000000010101 -> binary representation 8 bits 8+8=16 16+8=24 8 bits
Suleyman Demirel University, 2011 Network Address is: • 192. 168. 1. 0/24
Suleyman Demirel University, 2011 Host Address is: • 192. 168. 1. 21/24
Suleyman Demirel University, 2011 Broadcast Address Prefix, identifies that Network Address consists of 24 bits starting from the left side. • 192. 168. 1. 21/24 • 11000000. 10101000. 000000010101 -> binary representation 8 bits Belongs to host’s range 8+8=16 16+8=24
Suleyman Demirel University, 2011 Broadcast Address • 11000000. 10101000. 000000010101 • Combination range of last octet: • 0000 - > first combination. . . • 1111 - > last combination
Suleyman Demirel University, 2011 Broadcast Address • Last combination of Host Part in IPv 4 address is called broadcast address • This is Broadcast address: • 192. 168. 1. 255
Suleyman Demirel University, 2011 Review • Given information: 192. 168. 1. 21/24 • Network address: 192. 168. 1. 0/24 • Host address: 192. 168. 1. 21/24 • Broadcast address: 192. 168. 1. 255/24 • Range of usable IP addresses: 192. 168. 1. 0 -192. 168. 1. 255
Suleyman Demirel University, 2011 Different types of communication with IPv 4 Types of Communication Unicast Broadcast Multicast
Suleyman Demirel University, 2011 Unicast Communication • The process of sending a packet from one host to an individual host
Suleyman Demirel University, 2011 Unicast Communication
Suleyman Demirel University, 2011 Broadcast Communication • The process of sending a packet from one host to all hosts in the network
Suleyman Demirel University, 2011 Broadcast Communication
Suleyman Demirel University, 2011 When Broadcast is used: • Mapping upper layer addresses to lower layer addresses • Requesting an address • Exchanging routing information by routing protocols
Suleyman Demirel University, 2011 Multicast Communication • The process of sending a packet from one host to a selected group of hosts
Suleyman Demirel University, 2011 Multicast Communication
Suleyman Demirel University, 2011 When Multicast is used: • Video and audio distribution • Routing information exchange by routing protocols • Distribution of software • News feeds
Suleyman Demirel University, 2011 Reserved IPv 4 Addresses Range
Suleyman Demirel University, 2011 Host Addresses for Different Purposes Different Host Addresses Private IPv 4 Addresses Public IPv 4 Addresses
Suleyman Demirel University, 2011 Private IPv 4 Addresses • The private address blocks are: • 10. 0 to 10. 255 (10. 0 /8) • 172. 16. 0. 0 to 172. 31. 255 (172. 16. 0. 0 /12) • 192. 168. 0. 0 to 192. 168. 255 (192. 168. 0. 0 /16) Private IP Addresses can not be used in Public Network (internet)

Suleyman Demirel University, 2011 Example of IPv 4 Addressing
Suleyman Demirel University, 2011 Question • Who assigns IP addresses?
Suleyman Demirel University, 2011 Answer • IANA – Internet Assigned Numbers Authority
Suleyman Demirel University, 2011 IANA - http: //www. iana. net • IANA is the master holder of the IP addresses. • The IP multicast addresses and the IPv 6 addresses are obtained directly from IANA. • Until the mid-1990 s, all IPv 4 address space was managed directly by the IANA.
Suleyman Demirel University, 2011 IANA - http: //www. iana. net • Nowadays IANA separated responsibilities to five Regional Internet Registries (RIRs)
Suleyman Demirel University, 2011 IANA and RIRs IANA Afri. NIC APNIC ARIN LACNIC RIPE NCC
