1 T ODAY I NTERNET A DDRESSING TCIP/IP I NTERNET PROTOCOL V4 L AB 7: C ONFIGURE IP ADDRESS

2 R EAL WORLD SITUATION Jessica is a Network Administrator She 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.

3 I NTERNET PROTOCOL : Agreed on instructions to allow computers to communicate

4 I NTERNET PROTOCOL : Many protocols exist for different tasks

5 I NTERNET PROTOCOL : Protocol suite: group of networking protocols that work together

6 TCP/IP PROTOCOL Protocol suite used for network communications Designed for the internet, now widely used Transmission Control Protocol and Internet Protocol

7 IP V 4 (I NTERNET PROTOCOL VERSION 4) Used to move data from one location to another

8 IP V 4 (I NTERNET PROTOCOL VERSION 4) One of main functions: help data packets find their way to the proper destination IP addressing 2 systems, IPv4 and IPv6

9 IP V 4 A DDRESSING Known as “best effort” delivery protocol Focus on getting data to correct location Not concerned if it does not get there

10 IP V 4 A DDRESSING Consists of network number and host number

11 IP V 4 A DDRESSING Used to identify a host/node Host/node = Name for computer, printer, network device associated with an IP address in TCP/IP network Name: Michael Student: ID #

12 IP V 4 A DDRESSING No 2 hosts on the same network can share the same IP address Name: Michael Student: ID # Name: Michael Student: ID #

13 IP V 4 A DDRESSING Numbers are computed in binary form and presented in decimal form Binary form: Decimal form:

14 C ONVERTING BINARY TO DECIMAL Decimal form =

15 C ONVERTING BINARY TO DECIMAL Binary form: Decimal form:

16 IP V 4 A DDRESSING Consists of four octetsoctets Octet = an eight-bit (or one Byte) value (32 bits long) Binary form:

17 IP V 4 N ETWORK C LASSES Classes identify which part is the network number, which is the host number Allows multiple uses IP address: IP address: Network ID Host ID

18 S UBNETTING Breaking up IP address to be used in more than one way IP address: IP address: Network ID Host ID

19 D O YOU KNOW YOUR AREA CODES ? (323)(562) (818) (949) (212)

20 IP V 4 N ETWORK C LASSES Class A: large networks always start with Ex: Class B: medium Start with Class C: small networks Start with Help us quickly identify a network Just like area codes help us identify a phone number: 310, 323, 562

21 S UBNET M ASK Used to determine to which subnetwork (network within a network)a particular IPv4 address belongssubnetwork 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: Class B subnet mask: Class C subnet mask:

22 I N CLASS LAB 7 a: Labsim 5.15 Configure IP addresses (5 points) b: Binary Conversion Activity(5 points) N EXT C LASS Configuring Host Addressing Labsim homework: 5.26
