ARP = Address Resolution Protocol
MAC = your network hardware device unique address

ARP tables can be modified so that packets can be redirected or diverted via a different machine by giving it false information on the MAC address. Another machine can pretend to be your machine and have your packets delivered to it instead.

>Could someone tell me what to do with it

Um, block it unless someone has further advice.
