I'm sorry, you cannot find a MAC address using a Serial Number. Mac address is related to network card. Nothing whatsoever to do with Serial Number. Each network device aka wired or wireless has its own hardwired mac address and this can be changed via software on some models. A Media Access Control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment. MAC addresses are used for numerous network technologies and most IEEE 802 network technologies, including Ethernet. Logically, MAC addresses are used in the Media Access Control protocol sub-layer of the OSI reference model.

MAC addresses are most often assigned by the manufacturer of a network interface card (NIC) and are stored in its hardware, the card's read-only memory, or some other firmware mechanism. If assigned by the manufacturer, a MAC address usually encodes the manufacturer's registered identification number and may be referred to as the burned-in address. It may also be known as an Ethernet hardware address (EHA), hardware address or physical address. Red Orchestra 2 Non Steam Cracking.

A network node may have multiple NICs and will then have one unique MAC address per NIC. MAC addresses are formed according to the rules of one of three numbering name spaces managed by the Institute of Electrical and Electronics Engineers (IEEE): MAC-48, EUI-48, and EUI-64. The IEEE claims trademarks on the names EUI-48 and EUI-64, in which EUI is an acronym for Extended Unique Identifier. For wired and wireless cards that are removable it is often listed on a sticker directly on the device. @Random832 thank you, ure taking the words out of my mouth. The only network devices which could 'know' your notebook's MAC address are devices your notebook was connected to. If it was an ethernet network, the MAC of your network card, if it was a wireless network, your wifi adapter.

Each networking unit has its own MAC. For example, my notebook has MAC addresses from 3 physical devices: Wired ethernet, wireless LAN and bluetooth. So if you have been in other networks than your own, maybe you can get the MAC from there. – May 11 '15 at 17:02.
