FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Each IP datagram contains a Source Address and a Destination Address. The Destination Address in a given IP datagram is used to route that datagram to its destination(s). IP supports both unicast (i.e. point-to-point) and multicast (i.e. one-to-many) transmissions.

Detailed explanation-2: -IP is responsible for delivering the packets from source to destination, and regardless of the version being used, packets must use some form of addressing to uniquely identify the message source and message destination. This is very similar to the way that you address a letter that you send through the post.

Detailed explanation-3: -Each IP packet contains both a header (20 or 24 bytes long) and data (variable length). The header includes the IP addresses of the source and destination, plus other fields that help to route the packet. The data is the actual content, such as a string of letters or part of a webpage.

Detailed explanation-4: -Source IP-The source IP address for traffic from which traffic is forwarded (Any, Single Address or Address Range). Destination IP-The IP address of the server to which traffic is forwarded. Internal Port-To which port traffic will be forwarded.

Detailed explanation-5: -The header contains the source address, a destination address, protocol, and packet number. The protocol helps identify what type of packet is being transferred, whether it is an email, a web page, a video, etc.
