Explanation

In this scenario, the MAC address 00e0-fc99-9999 is associated with multiple IP addresses through dynamic ARP learning, indicating that the host's IP has changed several times. The ARP table on the switch shows multiple entries with different IPs mapped to the same MAC address, which is common when a device frequently updates its IP. As ARP is a dynamic protocol, these entries reflect the device's current and past IP associations.
