There are a couple of completely legitimate (read: white hat) reasons for MAC spoofing as well:
What is a passthrough mac address windows#
However, almost all popular platform such as Windows or OS X or Linux (and hence Android) support changing MAC addresses and pretty easily too. Each NIC is assigned a unique hard-coded MAC addresses that cannot be changed. All devices capable of networking (smartphones, laptops, routers) have one of these. The device that you’re looking at right now has a network interface controller (NIC), the thing that’s responsible for allowing you to connect to a network, like the internet. "ipconfig/all" command is used to know physical address of the device.Read this one first to you fully understand how MAC addresses work. Similarly "rarp" command is used to convert physical address to the IP address. Similar to IP addresses, there are some MAC addresses defined for special purposes,For example FF:FF:FF:FF:FF:FF is reserved ror broadcast purpose.Ĭommands to know what mac address system hasĪbove command lists out all the IP addresses and their physical addresses attached to the system where command is issued. MAC is the foundation for IP address to communicate packet from one system to the other. MAC address is very essential for the IP layer to work. The first three pairs of digits represent manufacturer(called OUI-Organisationally Unique Identifier) and last three pairs of digits represent number specific to the device(called NIC-Network Interface Controller Specific).ĪRP,Address Resoultion Protocol is used to convert IP address to the MAC address.
MAC address represent manifacturer of the card and device number. Remember Hexadecimal digits can be numbers from 0-9 and letters from A-F. MAC address is composed of 48 bit or six hexadecimal digits,separated by colons or dashes. It is "burnt into" the device by manufacturer of the device or Card. MAC address is unique to network device wanting to utilize TCPIP network or LAN or WLAN service. MAC address is also referred as physical address or hardware address or ethernet address. MAC address stands for Medium Access Control Address. What is IP address ,what is MAC address, networking devices which include hub, switch, Vs packet switching, TCP/IP protocol fields, ARP/RARP protocol fields, This tutorial covers everything one like to know about networking basics including circuit switching
