"The IP address is like a phone number that your computer uses to talk to devices attached to the network."
"In other words, an IP address is like a full address for postal mail while a MAC address is just the house number. For example, there are many addresses with a house number of 898 but there is only one address for 898 5th Ave, New York, NY United States . Simply mailing something to "898" will not get it there but "898 5th Ave, New York, NY, United States" is a globally unique address. "
"It is vital that you understand this before proceeding! The MAC address can be likened to the address of your building, '12 Router Avenue'. The destination IP address is like the name of your company. The router is the mailperson that stands in your street and shouts 'Where do I deliver mail for Evil Linux Routing Tricks INC?'. Your receptionist would then shout back 'Give it to the people over at 12 Router Avenue', which would prompt the mailperson to deliver mail at that building."
