This document provides information on IP addressing including: - IP versions 4 and 6, their address formats, and the differences between them. IP version 4 uses 32-bit addresses divided into 4 octets while version 6 uses 128-bit addresses divided into 8 portions of 16 bits each. - The classes of IP addresses (A, B, C) and how they relate to network size. Class A is for large networks, B for medium, and C for small networks. - How the network and host parts of an IP address are used, with the network part identifying the network and the host part identifying a specific device on that network. - An overview of private IP address ranges that are not

1. Wellcome To Presentation

2. IP ADDRESSING
Protocol
TCP/IP, NetBIOS(Microsoft)
TCP/IP-http, ftp, DNS.
What is IPAddressing
Unique name for each device
LAN Example
Logical Address
Network Layer Address (Layer 3)

4. IP Version
.
 IP version 4 (32 bit address)
 IP version 6 (128 bit address)

5. IP Version 4 Format
• IP Version 4
Bit is represented by 0 or 1 (Binary)
IP address ins binary from (32 bits)
01010101.00000101.10111111.00000001
32 bits are divided into 4 octets.
01010101.00000101.10111111.00000001
IP Address in decimal from:
85.5.191.1
Decimal from for easy format and readble
Computer understands only binary

6. IP Version 6 Format
• IP Version 6
Total 128 bit address
16 bit in each block
8 octets/ portion in total
16 bit converted to 4 digit hexadecimal
number
 Each portion is separated by colons
FD00:0DB8:7654:3210:2C4C:BA17:7124
:0032
For Future Use

7. IP Version 4 Format
•Minimum Number in each portion is 0(00000000 in
binary)
•Maximum number in each portion is 255(11111111
in binary)
•Range of IP address is 0 to 255
•More then 255 is not applicable
•Check by 100.256.1.0
•Total IP address range of IPV4 is 0.0.0.0 to
255.255.255.255

8. IP Version 4 Classes (IPv 4)
E 240.0.0.0 255.255.255.255 Reserved for Research

9. IP Version 4 Classes (IPv 4)
 Class A,B,C – LAN/WAN
 Class D – Multicasting
Class E- Reserved for future research and development.

10. Identifying IP Class
•See only first portion of any IP
•Example:
192.168.10.10- C Class.
150.12.10.10 – B Class
100.10.10.10 – A Class

11. Types of Data Communication
Generally, 3 types of communication in network
 Unicast- One to One
 Broadcast- One to all
 Multicast- One to group.

12. Unicast Communication
• One to one communication in a network
• Example (network types. PNG)
• Most communication is default one-to-
one communication.

13. Broadcast Communication
• One to all communication in a network.
• Example (network types.PNG)
• 200 devices connected in a LAN.
•Universal broadcast address is 255.255.255.255

14. Multicast Communication
• One to a group communication in a network.
• Example (network types.PNG)
• Suppose 100 devices are connected in a LAN
• Total 10 groups (each contains 10 devices)
• Example: Video Conference, Online live, streaming, etc.
• D class IP identifies multicast traffic/group
• Multicast is not included into CCNA course.
• We can not use it in LAN or WAN (check by putting 224 in first
portion of IP)
