Suppose,
My host is A
A(my machine) has ip address 12.
B has ip address 13
C has ip address 14
My machine has below entries in ARP cache
B => ip address 13 and its corresponding MAC address
C => ip address 14 and its corresponding MAC address
Now, B and C disconnects from LAN and when they are connected back to LAN, but this time C is assigned IP address 13 and B is assigned IP address 14
But my ARP cache has old info. What would happen if I try to ping B now ?
