| fea681da MK |
32 | .SH DESCRIPTION |
| 33 | This file is a plain ASCII file, describing the various DARPA internet | |
| c13182ef MK |
34 | protocols that are available from the TCP/IP subsystem. |
| 35 | It should be | |
| fea681da | 36 | consulted instead of using the numbers in the ARPA include files, or, |
| c13182ef MK |
37 | even worse, just guessing them. |
| 38 | These numbers will occur in the | |
| d394fbfc | 39 | protocol field of any IP header. |
| fea681da | 40 | |
| d394fbfc | 41 | Keep this file untouched since changes would result in incorrect IP |
| c13182ef MK |
42 | packages. |
| 43 | Protocol numbers and names are specified by the IANA | |
| fea681da MK |
44 | (Internet Assigned Numbers Authority). |
| 45 | .\" .. by the DDN Network Information Center. | |
| 46 | ||
| 47 | Each line is of the following format: | |
| 48 | ||
| 49 | .RS | |
| 50 | .I protocol number aliases ... | |
| 51 | .RE | |
| 52 | ||
| 53 | where the fields are delimited by spaces or tabs. | |
| 54 | Empty lines are ignored. | |
| 55 | If a line contains a hash mark (#), the hash mark and the part | |
| 56 | of the line following it are ignored. | |
| 57 | ||
| 58 | The field descriptions are: | |
| fea681da MK |
59 | .TP |
| 60 | .I protocol | |
| c13182ef | 61 | the native name for the protocol. |
| d394fbfc MK |
62 | For example |
| 63 | .IR ip , | |
| 64 | .IR tcp , | |
| 65 | or | |
| 66 | .IR udp . | |
| fea681da MK |
67 | .TP |
| 68 | .I number | |
| d394fbfc | 69 | the official number for this protocol as it will appear within the IP |
| fea681da MK |
70 | header. |
| 71 | .TP | |
| 72 | .I aliases | |
| 73 | optional aliases for the protocol. | |
| 74 | .LP | |
| 046495ca | 75 | This file might be distributed over a network using a network-wide |
| fea681da | 76 | naming service like Yellow Pages/NIS or BIND/Hesiod. |
