(8) Internet numbers & IP protocols types IP Protocol Numbers and Traffic Types At the end of this episode, I will be able to: 1. Identify and explain the purpose of IP protocol numbers and traffic types, given a scenario. Learner Objective: Identify and explain the purpose of IP protocol numbers and traffic types, given a scenario. Description: In this episode, the learner will examine IP protocol numbers used in IP headers to identify upper level protocols. We will also explore traffic types such as unicast, broadcast and more. Internet Protocol (IP) types ◦ Internet Control Message Protocol (ICMP) ▪ IP Protocol ID - 1 ◦ Internet Group Management Protocol (IGMP) ▪ IP Protocol ID - 2 ◦ Transmission Control Protocol (TCP) ▪ IP Protocol ID - 6 ◦ User Datagram Protocol (UDP) ▪ IP Protocol ID - 17 ◦ Generic Routing Encapsulation (GRE) IP Protocol ID - ◦ Internet Protocol Security (IPSec) ▪ Authentication Header (AH) IP Protocol ID - 51 ▪ Encapsulating Security Payload (ESP) IP Protocol ID - 50 Traffic types ◦ Unicast - one-to-one communication ◦ Multicast - one-to-many communication ◦ Broadcast - one-to-all communication ◦ Anycast - one-to-the-best communication  Additional Resources: ◦ IANA IP Protocol Numbers - https://www.iana.org/assignments/protocol- numbers/protocol-numbers.xml The protocol numbers are single-byte numbers used to identify transport protocols like TCP or UDP in the IP header. In the IPv4 header, you will find the protocol number in the “protocol field,” whereas, in IPv6, you will find the protocol number in a “Next header” field. The most common transport protocol like TCP and UDP uses 6 and 17 protocol number.
