What is MAC Adress

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. A network node may have multiple NICs and will then have one unique MAC address per NIC.

HOW to Find out Your MAC address?

Method 1

Click on Start>>Run>>CMD>>Ipconfig/all

A mac address contains 6 pairs of digits which is hexadecimal digits,The first three pairs of digits in the MAC address are called the OUI (Organizational Unique Identifier), which identifies the company that manufactured or sold the device. For example, a MAC address that begins with 00:1F:33 denotes a Netgear product. The last three pairs of digits are specific to the device and can be more or less considered a serial number of sorts. Together, the two parts of the MAC address form an ID that's unique to a particular device.

Dos Commands For System Managers

Here are some useful Dos commands For system administrators




Networking
ipconfig – Windows IP Configuration
This has to the DOS command I use most today. ipconfig will tell you the IP settings for the current computer such as what your current IP is and what subnet/gateway you are on. It is great for troubleshooting. Here are the two most useful commands for ipconfig and usage:
ipconfig /release – This will release any IP information that the computer was given and make your IP address 0.0.0.0


ipconfig /renew – 
This will ask any DHCP servers (usually your modem/router) for a new IP address.
ping – Check a connection or computer
Ping is used to check the health of a connection. The ping command will tell you whether a network device is responding and how fast it is running. The ping tool can also be used to convert a web address into an IP (eg. www.google.com = 74.125.19.99). Usage:
ping www.google.com – Pings a webserver to see if it can be reached or is responding. I personally use this to see if the computer I am on can reach the internet.
ping 192.168.0.1 – Pings a local address, often a modem, router or another computer.

netstat – Displays current TCP/IP connections
netstat – Will display what connections are currently active on the system. Useful for spotting programs calling back to base such as spyware.
