When ARP cache is updated?

Last updated on April 4, 2022

        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 ?
