1-8 INTERNET PROTOCOL NUMBER AND TRAFFIC TYPES

Question 1

What are the types of Internet Protocol (IP)?

Answer 1

• Internet Control Message Protocol (ICMP)
• Internet Group Management Protocol (IGMP)
• Transmission Control Protocol (TCP)
• User Datagram Protocol (UDP)
• Generic Routing Encapsulation (GRE)
• Internet Protocol Security (IPSec)

IP types are essential for understanding different communication protocols within networking.

Question 2

What is the IP Protocol ID for Internet Control Message Protocol (ICMP)?

Answer 2

1

ICMP is used for error messages and operational information in network communications.

Question 3

What is the IP Protocol ID for Internet Group Management Protocol (IGMP)?

Answer 3

2

IGMP is used for managing the membership of Internet Protocol multicast groups.

Question 4

What is the IP Protocol ID for Transmission Control Protocol (TCP)?

Answer 4

6

TCP is a connection-oriented protocol that ensures reliable communication.

Question 5

What is the IP Protocol ID for User Datagram Protocol (UDP)?

Answer 5

17

UDP is a connectionless protocol that allows for faster transmission without reliability.

Question 6

What is the IP Protocol ID for Authentication Header (AH) in IPSec?

Answer 6

51

AH provides connectionless integrity and authentication for IP packets.

Question 7

What is the IP Protocol ID for Encapsulating Security Payload (ESP) in IPSec?

Answer 7

50

ESP provides confidentiality, along with integrity and authentication for IP packets.

Question 8

What are the types of traffic in networking?

Answer 8

• Unicast
• Multicast
• Broadcast
• Anycast

These traffic types define how data is transmitted across a network.

Question 9

Define Unicast traffic.

Answer 9

one-to-one communication

Unicast sends data from one sender to one specific receiver.

Question 10

Define Multicast traffic.

Answer 10

one-to-many communication

Multicast sends data from one sender to multiple specific receivers.

Question 11

Define Broadcast traffic.

Answer 11

one-to-all communication

Broadcast sends data from one sender to all possible receivers in a network.

Question 12

Define Anycast traffic.

Answer 12

one-to-the-best communication

Anycast sends data from one sender to the nearest or best receiver in a group.

Question 13

What is the IP Protocol ID for Generic Routing Encapsulation (GRE)?

Answer 13

47

GRE is used to encapsulate a wide variety of network layer protocols.
