ARP - Proxy ARP best practices

ARP - determining the next hop MAC address


Proxy [ARP](/arp) is a technique used by a router or a network device to respond to ARP requests on behalf of another device, typically located on a different network segment or subnet. The primary purpose of Proxy ARP is to help devices in separate subnets communicate with each other without requiring the client devices to be explicitly configured with a default gateway.
