IT283__Unit_4.docx    Networking with TCP/IP Unit Assignment #4  Purdue University Global   IT283: Networking with TCP/IP    Unit Assignment #4 Part One:  1. In a short essay, explain the difference between the ICMPv4 and ICMPv6.  Both ICMPv4 and ICMPv6 share many similarities, but the header is different in each one.   ICMPv6 header includes Neighbor/router discovery, PMTU, and more that the ICMPv4 do not include.  “Message types that previously used other protocols now use ICMPv6, and new message types have been created that didn't exist in ICMPv4. For instance, Multicast Listener Discovery (MLD) is integrated as an ICMPv6 sub-protocol. ICMPv6 takes on a much larger role than ICMPv4.” (Tittel, J.L.C.L.C. E. 2012).  2. In a short table/graphic, outline three ICMPv4 error messages. Include the Message   Type, Type Number, and description.  Note: Information was taken from “Computer Networking Notes”.  Message Type  Type Number  Description  3  6  Destination Network Unknown  5  3
