With MAC addresses, there is no hierarchy, and thus packet forwarding would not be possible. So, MAC addresses are not used for packet transfer. I don’t think it sits there for no reason. So my question is, where exactly does a MAC address come into play during a packet transfer? Where indeed? What is the specific function of the MAC address?

A Reader Asks: What's a MAC Address?
A while back I saw an article of yours that described how to properly set up a secure wireless network. Based on that, I replaced my aging router with a new wireless router, and I implemented all of your security suggestions. I'm using WEP with 256-bit encryption, and I'm not broadcasting my SSID.
My router also offers something called MAC address filtering. According to the documentation, this would restrict access to the network to only the PCs that have been registered with the router. So even if someone managed to get my WEP key, they still wouldn't be able to connect to my network.
I know what my IP address is and tried using that, but it didn't work. Exactly what is a MAC address, and how do I find it?
Our Small Business Networking Expert Explains 'MAC Address'
MAC is an acronym and stands for Media Access Control. Excel viewer for mac. The MAC address (also known as the physical address) is your computer's unique hardware number. When you're connected to the Internet from your computer (or the 'host'), a correspondence table relates your IP address to your computer's physical (MAC) address on the LAN. This is how the router knows where to send IP packets destined for your system.
On a PC or a laptop with an integrated network adapter, you need to find it using software. The process is almost identical to the utility you use to see your systems IP address. On a Windows 2000 or Windows XP machine you would use IPCONFIG. To see the MAC address, you need to add /ALL to the command.

Because there are millions of networkable devices in existence, and each device needs to have a unique MAC address, there must be a very wide range of possible addresses. For this reason, MAC addresses are made up of six two-digit hexadecimal numbers, separated by colons. For example, an Ethernet card may have a MAC address of 00:0d:83:b1:c0:8e. Fortunately, you do not need to know this address, since it is automatically recognized by most networks.
