Detailed explanation-1: -The router uses the information in the IP header to decide whether and where to forward each received packet, and which network interface to use to send the packet. Most packets are forwarded based on the packet’s IP destination address, along with routing information held within the router in a routing table.
Detailed explanation-2: -The router examines its routing table, which identifies all the IP networks the router can forward packets to. It is then able to identify an exit interface to use in order to forward the packet towards the destination network identified in the packet.
Detailed explanation-3: -Routers got their name because they route IP Packets across networks: a router device connects different links. It examines IP packet headers, looking at the destination address and consulting a routing table of known networks. The table indicates which connections to send the packet on as the next link.
Detailed explanation-4: -PUBLIC AND PRIVATE IP ADDRESSES Public IPs are used by routers and by computers connected directly to DSL modems without a router. Private IP addresses are special IP addresses that are known only to a router and its home network. A Web server will not deliver Internet data to a private IP address.
