What is an IP packet?
An IP packet is a network data packet using Internet Protocol (IP) format.
What is the role of the address field in a packet travelling through a datagram?
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.
Which protocol creates the final IP packet?
The IP protocol creates all IP packets.
Are both UDP and IP unreliable to the same degree?
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.
Which field of the IP Packet indicates the remaining life of the packet?
TTL- Time To Live
What information is used at each hop to determine where the packet will be forward to?
ip packet header
What data can an ip packet contain?
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.
In tcp ip the protocol that garuntees packet delivery is ip?
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.
What is diffirence between static and dynamic friewall?
Static vs Dynamic Filtering -- Static (constant and unchanging) packet filtering offers security against novice hackers. You can configure the filtering rules when you install a firewall to filter based on source/destination IP addresses. This sets up a static filter. But static packet filtering does not have the intelligence to selectively open and close ports; it can either open all the non-private ports or close them all. If all ports are kept open, an intruder can break in; if all ports are closed, the firewall becomes obtrusive to the users on the network. (To see why ports are opened, see the section on FTP Security, below.) Dynamic filter
Which portion if the destination IP address is used as a packet is routed through the Internet?
Which portion of the destination IP address is used as a packet is routed through the Internet?
What information is used at each hop to determine where the packet will be forwarded next?
ip packet header
Receives a packet that is destined for 192.168.1.4 How will router treat the packet?
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.
