Host specific routing means t o first check if the destination address is on the same network as that of source address. The information about network of destination address is obtained using ARP(Address Resolution Protocol). If they both are on same network, the packet is forwarded directly, but if they are on different network, then a router is used to forward packets. The nearest router is traced by comparing metrics of different hops on the routing table for that destination address.
