0

I am referring the List of IP protocol numbers based on the wikipedia page but the number 84 seems appeared two times, is it a bug. I have to use this inside my javascript program.

Here is the relevant part of the list from wiki page.

0x52    82  SECURE-VMTP     Secure Versatile Message Transaction Protocol   RFC 1045
0x53    83  VINES   VINES   
0x54    84  TTP     TTP     
0x54    84  IPTM    Internet Protocol Traffic Manager   
0x55    85  NSFNET-IGP  NSFNET-IGP  
0x56    86  DGP     Dissimilar Gateway Protocol     
0x57    87  TCF     TCF

@Ramhound - these are not port numbers, but rather protocol numbers. I would have thought that yes, this would be a problem. – Attie – 2018-03-06T16:15:36.367

@Ramhound These are not port numbers, they are IPv4 protocol numbers. TCP has number 6, IDP is 17, etc. – Johan Myréen – 2018-03-06T16:15:42.460

@Ramhound From the wiki page I can see it's Protocol Number not port. – Haris – 2018-03-06T16:16:44.183

I wasn't paying enough attention. The original source of the table, IANA, doesn't even provide a valid reference. – Ramhound – 2018-03-06T16:17:33.370

Here I reproduce the answer given in dslreports.com forum by the user LinkLogger :

As to not leave an unanswered question lingering here I got in touch with the guys at Rockwell Collins and had an interesting conversation about this, but to summarize all of the computers and radios using TTP are long since gonzo but even recently (2011) IESG wanted to keep TTP and IPTM listed for 84, no doubt the result of a decision by committee, but the fact remains that TTP is deprecated and protocol 84 really only means IPTM (Internet Protocol Traffic Manager).

To support this answer. It was Jim Stevens who indicated the protocols for that particular protocol value. Mr. Stevens contact information indicates he works/worked for Rockwell Collins. – Ramhound – 2018-03-06T16:19:29.157
