A MAC address is an unique 48-bit hexadecimal identifier assigned by a manufacturer to a networking device such as a network card when it is manufactured. First six numbers a MAC address comprise the Organizational Unique Identifier and are assigned by the IEEE, the last six numbers represent the interface serial number. MAC addresses are usually written as six groups of characters; normally they look something like 00:D0:D7:10:5B:84 or 00-D0-D7-10-5B-84.
Utility ipconfig allows you to view network configuration information. Ipconfig shows your IP address, MAC address and other information.
ipconfig [/? | /all | /renew [adapter] | /release [adapter] | /flushdns | /displaydns | /registerdns | /showclassid adapter | /setclassid adapter [classid] ] where adapter Connection name (wildcard characters * and ? allowed, see examples) Options: /? Display this help message /all Display full configuration information. /release Release the IP address for the specified adapter. /renew Renew the IP address for the specified adapter. /flushdns Purges the DNS Resolver cache. /registerdns Refreshes all DHCP leases and re-registers DNS names /displaydns Display the contents of the DNS Resolver Cache. /showclassid Displays all the dhcp class IDs allowed for adapter. /setclassid Modifies the dhcp class id. The default is to display only the IP address, subnet mask and default gateway for each adapter bound to TCP/IP. For Release and Renew, if no adapter name is specified, then the IP address leases for all adapters bound to TCP/IP will be released or renewed. For Setclassid, if no ClassId is specified, then the ClassId is removed. Examples: > ipconfig ... Show information. > ipconfig /all ... Show detailed information > ipconfig /renew ... renew all adapters > ipconfig /renew EL* ... renew any connection that has its name starting with EL > ipconfig /release *Con* ... release all matching connections, eg. "Local Area Connection 1" or "Local Area Connection 2"
Result of using ipconfig /all shows the mac addresses. You should see something similar to the output below.
