Allow me to explain a little better. MAC stands for Media Access Control,
and it is a common way of giving network devices a hardware address. Each
device has one, sorta like latitude and longitude coordinates on a map. Each
device gets one that is unique and unchanging, and only the next device or
devices that see your device will ever know about it. To talk further down
the chain, you need an address that can be passed along, and that is what IP
is. It's like sticking house numbers onto those map coordinates. They both
mean the same thing, just that one is easier to pass around. MAC is only
good for talking between points A and B which are directly connected to each
other on a cable or a wireless link. IP allows you to stretch your
communications from point A to point Z way on the other side of the net.
Another way to look at is is using a bucket brigade. MAC gets the bucket
(your data) between individual people (network devices) in the chain, and IP
makes sure the bucket goes all the way down the chain end to end.

So they are only readable by your own modem or router??

MAC addresses are only readable by the next device physically connected to
you. They cannot propogate the same way an IP address can.

The MAC address sounds a little scary, kind of like the "fritz-chip"
That is "personally identifying information" if it is unique.
Can just any website grab the MAC address of people's computers?
Is there anyway to limit who has access to it?
