If you're using Windows XP, open a command prompt and type: ipconfig /all About half way down you'll see "physical address . . . . . . . . xx-xx-xx-xx-xx-xx" That's your mac address. If you were to look at your network card, that's also the physical address that would be on the label.
Define and describe the two parts of a mac address?
The first 6 digits is the OUI(Organizationally Unique Identifiers given by vendors and then the last 6 digits are used to represent the NIC uniquely with the OUI value.
Which part of the address is unique to each manufacturer?
The MAC address, also known as a physical address in Microsoft Windows, is unique to every NIC in the world. The first 3 hex digits are the manufacture's code. For example the mac address AA-BB-CC-11-22-33, AA-BB-CC would be the manufactures ID, and your bit would be 11-22-33.
How many bytes first 6 characters of mac address?
A MAC address consists of 12 hexadecimal characters, representing 6 bytes in total. The first 6 characters of a MAC address represent the Organizationally Unique Identifier (OUI) and correspond to 3 bytes. Therefore, the first 6 characters of a MAC address occupy 3 bytes.
Can a MAC address start a number other than 0 or 1?
Yes, a MAC address can start with a number other than 0 or 1. MAC addresses are typically represented in hexadecimal format, which includes digits from 0 to 9 and letters from A to F. Therefore, a MAC address can begin with any hexadecimal digit, including 2 through F.
What constitutesthe serial number portion of the MAC address?
The serial number portion of a MAC address is typically represented by the last three bytes (24 bits) of the address. In a standard MAC address, which is usually formatted as six groups of two hexadecimal digits (e.g., 00:1A:2B:3C:4D:5E), the first three bytes (the Organizationally Unique Identifier or OUI) identify the manufacturer, while the last three bytes serve as a unique identifier assigned by the manufacturer to each network interface card (NIC). This ensures that each device has a unique MAC address within its network.
What is the first 24 bits in a mac address called?
