Every interface on the 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 9 MAC Media Access Control address To allow a computer to determine which packets are meant for it each computer attached to an Ethernet network is assigned a 48 bit integer known as its MAC address also called an Ethernet address hardware address or physical address They are normally written as eight hexadecimal numbers such as 00 71 88 af 12 3e 0f 01 Ethernet hardware manufacturers purchase blocks of MAC addresses and assign them in sequence as they manufacture the Ethernet interface hardware Thus no two hardware interfaces have the same MAC address 10 Packet A packet is the unit of data sent across a physical network It consists of a series of bits containing data and control information including the source and the destination node host address and is formatted for transmission from one node to another 11 Ping Ping sends an ICMP echo request message to a host expecting an ICMP echo reply to be returned Normally if a host cannot be pinged you won t be able to use Telnet FTP to connect to the host Conversely if Telnet or FTP cannot be used to connect to a host Ping is often the starting point to determine what the problem is
