Spoofing a MAC address involves changing the Media Access Control (MAC) address of a network interface on a device to impersonate another device or to conceal its true identity. This can be done for various reasons, such as bypassing network access controls, enhancing privacy, or evading security measures. By altering the MAC address, an attacker can gain unauthorized access to networks or avoid detection by network monitoring systems. However, it's important to note that spoofing can be illegal and unethical when used for malicious purposes.

What is the difference between mac spoofing and arp spoofing?
MAC spoofing involves changing the Media Access Control (MAC) address of a network interface to impersonate another device on a local network. In contrast, ARP spoofing targets the Address Resolution Protocol (ARP) by sending false ARP messages, linking an attacker’s MAC address to the IP address of a legitimate device, which can lead to data interception or network disruption. While both techniques aim to deceive network protocols for malicious purposes, MAC spoofing focuses on the hardware address, whereas ARP spoofing manipulates the mapping between IP and MAC addresses.
What type of attack involves replacing a valid MAC address with an invalid MAC address on a local network?
ARP Spoofing
Can two computers have the same MAC address?
NO, its not possible to have same MAC addresses for two different network cards. because MAC address is a unique part of the recognition of the network card and it is also called as PHYSICAL address of your PC. There is possibility of 2 network cards with same MAC address by 3rd party MAC spoofing techniques.........
Can computers have the same MAC address on a server?
No, they can't have the same mac address, because mac address is an id for a machine therefore the ip addresses are registered to the DHCP table accordingly to the mac address. So if you spoof the mac address lets say having two machines with the same mac address what will happen is that only one machine at time would be allowed once it disconnect then the other can connect. Why spoofing a mac address? I guess one of the reasons is to defeat a network administrator when they secure their network by filtering the mac addresses so by spoofing the mac address you will be able to access the internet.
How does MAC address filtering enable wireless network security at the device level?
MAC address filter is a pretty secure way of rudimentary network security. Enabling it makes the network available only to know devices. However, this leaves it vulnerable to MAC address spoofing.
What is mean by Mac spoofing?
Every piece of equipment (computers, printers etc.) has a MAC (Media Access Control) address which identifies it when it is connected to a network. To spoof the MAC address is to supply the network with a different address than the one allocated for your computer so you are pretending to be another computer.
What is ip spoofing?
IP spoofing is the process by which an IP address is created in order to conceal the senders identity or impersonate another person's IP address. IP spoofing is a crime and punishable by law.
Why configure a static MAC address on a port interface?
Configuring a static MAC address on a port interface helps enhance network security and stability by preventing unauthorized devices from connecting. It ensures that only specific, predetermined devices can communicate through that port, reducing the risk of MAC address spoofing and other attacks. Additionally, it can improve network performance by minimizing unnecessary MAC address learning and flooding, as the switch already knows the MAC address associated with the port.
How do you implement ip spoofing?
Ip spoofing is done by modifying the source address of a ip packet from where it is initiated and spoofing another ip address of trusted host and sent to the destination selected as a victim. There are many application program available in the website through which we can spoof an ip address.
How do you find mac address of a remote system and how can we say its the correct onewhat is user changes his mac id?
To get the mac address you will need to use Address Resolution Protocol (ARP). Pretty much this will show an IP address and then give you the MAC address of that computers network card. As for the user changing it. Obviously you cant prevent a user from spoofing a MAC address, but as far as I am aware you cant change it permenently. So I dont think there is very much to worry about there. Also, unless you are dealing with technically minded people, I would doubt that they would even know how to spoof a MAC never mind change it (if its possible that is - which, like I have already said I really dont think it is)
Who assigns MAC address to NIC?
The mac address is the PHYSICAL address of your network card. Each network card is manufactured with a unique address which distinguishes it from every other network card in the world. 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.
Can you have a dynamic Mac address?
In general, the MAC address is tied to a specific piece of hardware and does not change. It is possible, however, under certain circumstances to change the MAC address. 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. Although intended to be a permanent and globally unique identification, it is possible to change the MAC address on most modern hardware. Changing MAC addresses is necessary in network virtualization. In this case, the MAC address of the actual NIC is hidden from the network and the network only sees the MAC assigned to the virtual NIC - which can be configured, with some finesse, to be dynamic. It can also be used in the process of exploiting security vulnerabilities. This is called MAC spoofing.
