TodayInternet AddressingTCIP/IPInternet protocol V4Lab 7: Configure IP address
Real 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.
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 Protocol • and 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/node Host/node = Name for computer, printer, network device associated 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:00011110.00111100.00010111.10011010 Decimal form:30.60.23.154
Converting binary to decimal Decimal form = 10.20.30.31
Converting binary to decimal 0 0 0 1 1 1 1 0 Binary form:00011110.00111100.00010111.10011010 Decimal form:30.60.23.154
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 IP address: 192.130.227.27 • Classes identify which part is the network number, which is the host number • Allows multiple uses Network ID Host ID IP address: 192.130.227.27 Network ID Host ID
Subnetting IP address: 192.130.227.27 • Breaking up IP address to be used in more than one way Network ID Host ID IP address: 192.130.227.27 Network ID Host ID
Do you know your area codes? (323) (562) (818) (949) (212)
IPv4 Network Classes Help us quickly identify a network Just like area codes help us identify a phone number: 310, 323, 562 Class A: large networks always start with 1-127 Ex: 125.10.1.55 Class B: medium Start with 128-191 Class C: small networks Start with 192-223
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
