REAL WORLD SITUATION
Jessica is a Network AdministratorShe works for a company that has purchased another company. She needs to make the 2 networks work together.To do this she will need to understand TCP/IP addressing.
INTERNET PROTOCOL:
Agreed on instructions to allow computers to communicate
INTERNET PROTOCOL:Many protocols exist for different tasks
INTERNET PROTOCOL:Protocol suite: group of networking protocols that work together
TCP/IP PROTOCOL
• Protocol suite used for network communications• Designed for the internet, now widely used• Transmission Control Protocoland Internet Protocol
IPV4 (INTERNET PROTOCOL VERSION 4) Used to move data from one location to another
IPV4 (INTERNET PROTOCOL VERSION 4) One of main functions: help data packets find their way
to the proper destination IP addressing 2 systems, IPv4 and IPv6
IPV4 ADDRESSING Known as “best effort” delivery protocol Focus on getting data to correct location Not concerned if it does not get there
IPV4 ADDRESSING Consists of network number and host number
IPV4 ADDRESSING Used to identify a host/nodeHost/node =Name for computer, printer, network deviceassociated with an IP address in TCP/IP network
Name:Michael
Student: ID #356-791
IPV4 ADDRESSING
No 2 hosts on the same network can share the same IP address
Name:Michael
Student: ID #356-791
Name:Michael
Student: ID #228-350
IPV4 ADDRESSING
Numbers are computed in binary form and presented in decimal form
Binary form: 00011110.00111100.00010111.10011010Decimal form: 30.60.23.154
CONVERTING BINARY TO DECIMAL

IPV4 ADDRESSING Consists of four octets Octet = an eight-bit (or one Byte) value(32 bits long)
Binary form: 00011110.00111100.00010111.10011010
IPV4 NETWORK CLASSES
Classes identify which part is the network number, which is the host number
Allows multiple uses
IP address:192.130.227.27
IP address:192.130.227.27
Network ID
Network ID
Host ID
Host ID
SUBNETTING
Breaking up IP address to be used in more than one way
IP address:192.130.227.27
IP address:192.130.227.27
Network ID
Network ID
Host ID
Host ID
DO YOU KNOW YOUR AREA CODES?
(323) (562) (818)(949) (212)
IPV4 NETWORK CLASSES
Class A: large networksalways start with 1-127Ex: 125.10.1.55
Class B: mediumStart with 128-191
Class C: small networksStart with 192-223
Help us quickly identify a networkJust like area codes help us identify a phone number:310, 323, 562
SUBNET MASK Used to determine to which subnetwork (network
within a network)a particular IPv4 address belongs Assigned to each host on a TCP/IP network Can be used to quickly identify the network class of an
IPv4 address Class A subnet mask: 255.0.0.0 Class B subnet mask: 255.255.0.0 Class C subnet mask: 255.255.255.0
