IP ADDRESS AND MAC ADDRESS

Fri Feb 17, 2017 1:59 pm

just wish to ask you guys ..if i got the concept correctly . Internet is interconnected through Routers. And every Router that is connected to ISP should have a PUBLIC IP ADDRESS. And routing table decide the shortest way to reach a destination Public IP address.

First Source Router is connected to the next Router using Routing table through next routers MAC address ( provided that two router are in same network). Now on reaching a destination public ip address ed Router . Routing table will convert that public ip address to private ip address. And it will be directed to nearest Switch using MAC Address. And that switch will once again reach the source computer in the private network using ARP message to all computer connected to that Switch. And only requested private ip address replied with its mac address and they share date.

Every ip address contain network address and physical address. in term of public ip address , network address contain the destination public ip address and physical address contain next MAC address of Router , which keep on changing till it reach destination IP address.
In term of private ip address, network address contain private ip address of computer within the network and the physical address contain the mac address of the particular port of that computer.
