Computers that interconnect two networks and pass packets from one to the other are called Internet Gateways or Internet Routers Gateways route packets that are based on the destination network not on the destination host 6 ICMP Internet Control Messages Protocol No system works correctly all the time ICMP provides a method of communicating between the Internet Protocol software on one machine and the Internet Protocol software on another It allows gateways to send error or control messages to other gateways or allows a host to know what is wrong with the network communication 7 Internet Physically the Internet is a collection of packet switching networks interconnected by gateways along with TCP IP protocol that allows them to perform logically as a single large and virtual network The Internet recognizes hosts using 32 bit IP address 8 IP Internet Protocol address Every interface on an Internet must have a unique IP address also called an Internet address These addresses are 32 bit numbers They are normally written as four decimal numbers one for each byte of the address such as 192 168 41 1 This is called dotted decimal notation GW 7472 User Manual Version 1 0 Dec 2010 56 9 MAC Media Access Control address To allow a computer to determine which packets are meant for it each computer attached to an Ethernet is assigned a 48 bit integer known as its MAC address also called an Ethernet address hardware
