   May 29, 2014 · The source MAC address is the MAC address of the sender's NIC. The destination MAC address is determined based on the routing process. If the destination IP address is on a different network segment, the sender's NIC uses the MAC address of the default gateway (router) to forward the packet.

   Does a NIC have a unique MAC address?

   • This is true for any number of NICs, irrespective of the medium. They all have their own MAC addresses and hence would acquire unique logical addresses. Mac address can change when installing a new ethernet card.Also when switching internet providers can change a mac address.

   Does a NIC change MAC address?

   • The MAC address of a NIC will never change. Once you are in a network it uses RARP to get its logical address from the network. Now say you install a new NIC and join a network (say the Internet). Each card will get their unique IPs provided by the ISP. So NIC-1 will mind its business and would not interfere with NIC-2 and NIC-2 would do the same.

   What happens if a router encapsulates a MAC address?

   • Once it obtains a MAC address the IP packet is encapsulated in a L2 frame and sent across the media. If the IP packet is meant for a host on a different subnet/ network, it will be sent to the default gateway, this router will de-encapsulate the L2 frame (remove and discard it) check the IP address and will forward it.

   Do I need a MAC address if I have an IP address?

   • Because when I have the IP address, I have the "address" )or the identity) of the host I want to talk to. No need to get the MAC address of the destination host. You also do not require MAC addresses when you talk to a computer in the public network - here also you just need the IP address.

   Jun 29, 2011 · A Static MAC address is one that has been manualy input (typed via a command) into the CAM or MAC address table. A dynamic MAC address is one that has been learned via an arp request. For example if a switch learns the MAC address from another device then it has dynamically sourced the MAC address.
