 | | For example, if you are at the Maths Department, and want to access quark on the Physics Department's LAN from your box, the networking software cannot send packets to quark directly, because it is not on the same Ethernet. |
 | | You will notice that we now have three different types of addresses: first there is the host's name, like quark, then there are IP-addresses, and finally, there are hardware addresses, like the 6-byte Ethernet address. |
 | | All these somehow have to match, so that when you type rlogin quark, the networking software can be given quark's IP-address; and when IP delivers any data to the Physics Department's Ethernet, it somehow has to find out what Ethernet address corresponds to the IP-address. |
