The built-in identifying address coded into a Network Interface Card (NIC) is called a MAC address. It is a unique identifier assigned to the hardware by the manufacturer and is used to identify devices on a network. MAC addresses are typically 48 bits long and are displayed in hexadecimal format.
Mac address
Doesn't matter if your connected to a LAN or not. The MAC address is hard coded into the NIC and does not change unless software on the computer requires that it changes.
MAC filtering
It is the 12 hexadecimal digit combination identifying the manufacturer and id of your NIC the first 6 digits is the OUI(Organizationally unique Identifier), this identifies the company that made the NIC the last 6 digits is the USI(Unique station identifier) this identifies your NIC A NIC identifier can only contain letters from A to F and numbers from 0 to 5 a NIC identifier, more commonly known as data-link layer address or MAC address looks like this: A6-D5-FF-5A-3D-6A
•What is the physical address (the MAC address) of the NIC (or network adapter) for this connection?
No, MAC addresss and IP address are not the same. MAC addresses are "hard-coded" into the Network Interface Card (NIC) and only ID that individual card. The IP address is software generated and ID's both the network and the individual host.
if by co you mean computer then yes you go to command prompt and type in "ipconfig/all" and you go to "network interface(or whatever it calls your nic)" and it will show u the physical address of your nic
