Hey

Can anyone please tell me what is ethernet address and its role in security. If someone knows my PC ethernet address, how would it affect my security? What can he do with that ethernet address?
I have some knowledge about IP address, many ways of tracing and hiding IP, but I don't know if ethernet address can also be traced. I really wanna know ethernet address is useful for what purpose? Thanks for any help.

Ethernet address is an address assigned to network interface cards by the manufacturer and they identify a computer or a machine.IP address is an address assigned to a machine connected to a network. The assignment of addresses can be static or dynamic. This is analogous to phone numbers assigned to each phone in a region.

Hey it is so easy Ethernet address is the physical address of the pc we cant change it and IP address is the given for identification of pc in network and we can change it.

Ethernet address specified in the manufacturer's network interface card and the address of the computer or their machine.IP address assigned to computers connected to the network is identified by the address. The assignment of addresses can be static or dynamic. This area is similar to phone numbers assigned to each phone.

An Ethernet address (or a physical address) is an address assigned to the network interface cards by the manufacturer and they uniquely identify a PC or a machine.
IP address (or logical address) is an address assigned to a machine connected to a network. The address assignment can be either static or dynamic. This is analogous to phone numbers allocated for each phone in an area.

Ethernet address, also called a MAC address is a 48-bit number used to identify each network computer. This address is usually written in hexadecimal. It is possible that you are thinking of a MAC vs. IP address. The IP address is an identifier for a computer or device on a TCP / IP. Networks using the TCP / IP through the messages based on the destination IP address. Form of an IP address is a 32-bit numeric address written in four digits separated by hyphens.

An Ethernet address (or physical address) is the address assigned by the manufacturer to the network interface card, and their uniquely identify a PC or a machine. IP address (or logical address) assigned to connect to the network address of the computer. Address assignment can be static or dynamic. This is similar to every region of the telephone dial phone number.

Ethernet address is the address of the manufacturer of your network, and identifies a computer or a machine.
The IP address is the address of the machine is connected to the network. address assignment can be static or dynamic. This is a reference telephone number assigned to each region.

You people provide nice knowledge about the ethernet address and IP address. I am not to much sure with this terms. This is really good to read about it. Nice as well as knowledgeable thread that you provide over here. I really appreciate you guys for your discussion over here.

They are two different things. Ethernet address, MAC address is commonly known as the identity of individual machines in the line and the method often used to allow or deny access to the network or Internet connection. That said, the MAC address filtering is not secure and anyone with a modicum of knowledge to ignore that just a few minutes. Therefore, WEP key has been introduced, which also revealed to be an easy target.
