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

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

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

16 8 4 2 1

Decimal form = 10.20.30.31

0 1 0 1 0

1 0 1 0 0

CONVERTING BINARY TO DECIMAL

Binary form:00011110.00111100.00010111.10011010Decimal form: 30.60.23.154

128 64 32 16 8 4 2 1

0 0 0 1 1 1 1 0

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

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
