How to clear the Address Resolution Protocol (ARP) cache in Windows 10

Address Resolution Protocol (ARP) is used to map MAC addresses to IP addresses. All hosts on the network will have their own IP address, but the network interface card (NIC) will have a MAC address rather than an IP address. ARP is a protocol used to associate IP addresses with MAC addresses. All these entries are collected and placed in the ARP cache. The mapped addresses are stored in cache and they usually do no harm.
