There are two address fields. Source is the IP address the packet came from and destination is the IP address the packet is meant to be delivered to.
The IP protocol creates all IP packets.
It's recorded at the top of the IP packet header. 16 bit source and destination port.
When IP sends a packet, it receives a confirmation for each packet and, if needed, rebroadcast the packet. This makes it reliable. UDP does not get confirmation. It broadcast each packet only once and assumes that it get to you. This makes it less reliable then IP because it does not check for problems or rebroadcast.
ip packet header
TTL- Time To Live
An IP packet can contain data about the format of the internet header and the abstract parameters such as the header checksum. The IP packets also provide an internet time stamp.
No, the protocol that guarantees packet delivery is TCP.No, the protocol that guarantees packet delivery is TCP.No, the protocol that guarantees packet delivery is TCP.No, the protocol that guarantees packet delivery is TCP.
Which portion of the destination IP address is used as a packet is routed through the Internet?
ip packet header
the router will enqueue the packet that is sent to the destination 192.168.1.4.and then that packet is sent on transmission media(cable).it checks every ip address that is holding the ip same as the destination ,if it reaches there then it deleiver it on that machine.
The delivery of Packet byDestination Computerin TCP\IP stack is reported by sending Acknowledgement to the Source Computerfor the received Packet by Destination Computer.
