IP Addresses

Question 1

What are the 2 IP Protocols? and what is some info about them?

Answer 1

Internet Protocol versions 4 and 6 (IPv4, IPv6). It is a Layer 3 protocol.
The IPv protocols are connectionless. There are no sessions formed when traffic is transmitted, the transmitter sends data to the receiver without a confirmation, no status information is sent back from the receiver to the transmitter.

Question 2

TCP is connectionless.

Answer 2

False, TCP is connection-oriented.

It sends data through the 3 way handshake.

Question 3

Explain the 3-way handshake.

Answer 3

Transmitter sends an SYN message to the receiver. The receiver sends an SYN-ACK message back to the transmitter and finally, the transmitter sends an ACK message to the Reciver.

Question 4

Explain a connectionless protocol.

Answer 4

There are no sessions formed when traffic is transmitted, the transmitter sends data to the receiver without a confirmation, no status information is sent back from the receiver to the transmitter.

Question 5

How are IP packets treated?

Answer 5

Independably. This is why traffic can take different paths to get to a destination.

Question 6

What do routers base the routing decisions on?

Answer 6

The Network portion of the hierarchical addressing structure.

Question 7

explain best-effort delivery.

Answer 7

IP only gives best-effort delivery. There is no guarantee that the packet will make it, each packet can be copied, misdirected, lost, and dropped and that should be expected in transmission.

Question 8

What data recovery features does IP have?

Answer 8

There isn’t any. The end devices should take care of this if the data gets corrupted and not the routers in between.

Question 9

If IP protocols don’t handle built-in sessions and retransmissions then who does?

Answer 9

Higher-level protocols such as TCP. TCP handles corrupt and misdirected packets.

Question 10

_____ route _____ based on ____

Answer 10

Routers route packages based on the destination address.
