MAC Ethernet Address

Disclaimer

This essay does not describe an existing computer program, just one that should exist. This essay is about a suggested student project in Java programming. This essay gives a rough overview of how it might work. I have no source, object, specifications, file layouts or anything else useful to implementing this project. Everything I have prepared to help you is right here.

This project outline is not like the artificial, tidy little problems you are spoon-fed in school, when all the facts you need are included, nothing extraneous is mentioned, the answer is fully specified, along with hints to nudge you toward a single expected canonical solution. This project is much more like the real world of messy problems where it is up to you to fully the define the end point, or a series of ever more difficult versions of this project and research the information yourself to solve them.

Everything I have to say to help you with this project is written below. I am not prepared to help you implement it; or give you any additional materials. I have too many other projects of my own.

Though I am a programmer by profession, I don’t do people’s homework for them. That just robs them of an education.

You have my full permission to implement this project in any way you please and to keep all the profits from your endeavour.

Please do not email me about this project without reading the disclaimer above.

MAC

Media Access Control

Some machines have several Ethernet cards and hence several IDs.

Some Ethernet cards allow you to modify the id by software, so the ID won’t necessarily be unique or fixed.

It is easy to replace an Ethernet card or to move it from machine to machine.

The MAC is considered secret. Ordinary Java will not access it. You cannot access it without running code on the machine with the Ethernet card. Internet protocols will not divulge it.

The notes in the MAC entry may help.
