MAC is medium access control address. IP is Internet Protocol. MAC is the hardware address and IP is software address. MAC is static in nature. Designed by the manufacturer. IP being a software address is dynamic in nature.

Mac is assigned to a network device,that can not be changed excepting manufacturer.
While,I.p. Can be changed,for every domain selected.

Actually, the MAC address isn't assigned at all, it's hard-coded into the chipset of the network device (NIC, Router, etc.). The only way to actually CHANGE a MAC address is to completely remove the device and replace it, or to change it in the device itself, you'd have to remove the chip from it's board, obtain a different chip, and solder it in the place where the original one was.
However, it is possible to mask your MAC address with software... (^_^)

MAC (Media Access Control) addresses uniquely identify Ethernet network cards (or PCs with built in Ethernet).
Although it's true that every computer that uses Ethernet has a unique MAC address, not all Internet connections are made
over Ethernet. Also, MAC addresses in a particular local network
are not similar in any way, so one can't use them to decide that a particular machine is "nearby."

IP addresses uniquely identify computers on the Internet, or on a local intranet. Computers on the same local "subnet,"
such as those on a particular local network, will share part of their IP address. For instance, computers in my office
intranet are part of the 192.168.2.x subnet, with IP addresses like and The router that
connects our office to the Internet has the IP address That router also has a true Internet IP address,
and performs NAT (Network Address Translation) to allow connections from computers inside my intranet to reach the outside
world... But blocks incoming connections for security.

Mac and Ip address both are address of the network card in your computer. The communication from a computer to other is done by the upper layer protocols( IP layers ). The Ip layers put use the ethernet technology to communicate. The ethernet tech is asscosiated with MAC address whereas the IP layers are associated with the IP addresses. There exists a ARP table which has a mapping of the IP and their corresponding MAC address. So when the ip layer requests coomunication over the ethernet technology the ethernet finds out the corresponding destination mac address and then communicates because it cannotunderstand the ip address given by the ip layer
