RFC 943
Assigned numbers
ASSIGNED NUMBERS 🎀
Network Working Group 🌸 this is the official RFC number 943, and it's all about the numbers that protocols use to talk to each other.
- Authors: J. Reynolds and J. Postel, both from ISI 💖
- Date: April 1985 📅
- Obsoletes RFCs: 923, 900, 870, 820, 790, 776, 770, 762, 758, 755, 750, 739, 604, 503, 433, 349 🙈
- Obsoletes IENs: 127, 117, 93
Bestie, this doc literally replaces a whole pile of older RFCs and IENs, so if you see any of those numbers in your reading list, this is the one that counts ✨
Status of this Memo 📝
This memo is an official status report on the numbers used in protocols in the ARPA-Internet community. Distribution of this memo is unlimited 🦋
Introduction 🧚
So this is a Network Working Group Request for Comments that lists the currently assigned values from several series of numbers used in network protocol implementations 💅 It's going to get updated every so often, but if you need the latest info, you can always go ask Joyce Reynolds. Joyce is also the one who handles number assignments, so if you're building a protocol or app that needs a link, socket, port, protocol, network number, etc., you reach out to Joyce to get your number 🫶
Here's Joyce's info, verbatim:
Joyce Reynolds
USC - Information Sciences Institute
4676 Admiralty Way
Marina del Rey, California 90292-6695
Phone: (213) 822-1511
ARPA mail: JKREYNOLDS@USC-ISIF.ARPAMost of the protocols mentioned here are documented in the RFC series of notes 📚 The more prominent and widely used ones are documented in the "Internet Protocol Transition Workbook" [35] or in the older "ARPANET Protocol Handbook" [36], which the NIC prepared. Some of the items listed are undocumented, which is so iconic and also kinda chaotic 💀 For more protocol info, check the memo "Official ARPA-Internet Protocols" [92] ✨
In every case, the name and mailbox of the responsible person is listed. In the lists that follow, you'll see a bracketed entry like [nn,iii] on the right-hand margin of the page. The "nn" part points to the document, and the "iii" part points to the person. Whenever possible, the letters are a NIC Ident as used in the WHOIS service 🍓
ASSIGNED NETWORK NUMBERS 🌈
The network numbers listed here are used as internet addresses by the Internet Protocol (IP) [35,80] 💜 IP uses a 32-bit address field and splits that address into a network part and a "rest," or local address part. The split comes in 3 forms, or classes ✨
The first type is class A. It has a 7-bit network number and a 24-bit local address. The highest-order bit is set to 0, which gives you 128 class A networks. Literally iconic 👑

0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
|0| NETWORK | Local Address |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
Class A AddressThe second type is class B. It has a 14-bit network number and a 16-bit local address. The two highest-order bits are set to 1-0, which gives you 16,384 class B networks 🦋

+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
Class B AddressThe third type is class C. It has a 21-bit network number and an 8-bit local address. The three highest-order bits are set to 1-1-0, which gives you 2,097,152 class C networks 🌸

+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
Class C AddressNote: No addresses are allowed with the three highest-order bits set to 1-1-1. These addresses (sometimes called "class D") are reserved. Not allowed, bestie 🚫
One commonly used notation for internet host addresses splits the 32-bit address into four 8-bit fields. Each field's value is written as a decimal number, with the fields separated by periods. This is called "dotted decimal" notation 🧁 For example, the internet address of USC-ISIF.ARPA in dotted decimal is 010.002.000.052, or 10.2.0.52.
The dotted decimal notation is used in the listing of assigned network numbers. Class A networks are written as nnn.rrr.rrr.rrr, class B networks as nnn.nnn.rrr.rrr, and class C networks as nnn.nnn.nnn.rrr. Here nnn stands for part or all of a network number, and rrr stands for part or all of a local address ✨
There are four categories of Internet Address users: Research, Defense, Government (Non-Defense), and Commercial 💅 To show how network identifiers are allocated across these categories, a one-character code goes to the left of the network number: R for Research, D for Defense, G for Government, and C for Commercial. (See Appendix A for more details on this division of network identification. 📖)
Network numbers are assigned to networks connected to the ARPA-Internet and DDN-Internet, and also to independent networks that use the IP family of protocols (these are usually commercial). Independent networks are marked with an asterisk in front of the number 🍓
The administrators of independent networks must apply separately for permission to interconnect their network with either the ARPA-Internet or the DDN-Internet. Independent networks don't need to be listed in the working tables of either the ARPA-Internet or DDN-Internet hosts or gateways 🙈
Sometimes the assigned numbers of networks change, for various reasons. To make the transition easier, the old number is listed for a transition period too. These "old number" entries are marked with a "T" after the number and before the name, and the network name gets the suffix "-TEMP" 🦋
Special Addresses 🧚
Sometimes it's useful to have fixed addresses with functional meaning instead of identifying specific hosts. When that's the case, the address zero is interpreted as meaning "this," as in "this network." An address of all ones is interpreted as meaning "all," as in "all hosts." For example, 128.9.255.255 could be read as meaning all hosts on network 128.9. Or 0.0.0.37 could be read as meaning host 37 on this network 💖

Okay bestie, so ports are what TCP [35,81] uses to name the two ends of a logical connection, the ones that carry long term conversations 💬 To help out callers who don't know who to talk to, a service contact port is defined. The port listed here is the one the server process uses as its contact port, and that contact port is sometimes called the "well-known port" ✨
To the extent possible, these very same port assignments are also used with UDP [35,79] 💜
The assigned ports only take up a small slice of all the possible port numbers. Every assigned port has all of its bits cleared to zero except for the low order eight bits 🫶 Those low order eight bits are the part that actually gets specified here.

256 Reserved [JBP]ASSIGNED ARPANET LINK NUMBERS 💖
Okay so, the word "link" here is not what you'd think 😭 It refers to a field in the original ARPANET Host/IMP interface leader. The link was first defined as an 8-bit field. Later specs turned that field into the "message-id", which is 12 bits long, and the name "link" now means the high order 8 bits of that 12-bit message-id. The Host/IMP interface itself is defined in BBN Report 1822 [8], so go check that if you want the full tea ☕
The low-order 4 bits of the message-id field are called the sub-link. Unless a particular protocol explicitly says otherwise, the sub-link has no sender-to-receiver meaning 🫶 The sender can use the sub-link however they like (the destination IMP sends it back in the RFNM), and the receiver should ignore it, no cap 🙈

96 01100000 DOD IP [35,79,JBP]Lowkey important: the IEEE 802.3 header has no type field to say what protocol is up next 🙈 As a workaround, you can put the Ethernet type field value in the IEEE 802.3 header's length field. Then, when a packet arrives, use this test to figure out how to process it.
If the value in the length field of the IEEE 802.3 header is greater than the Ethernet maximum packet length, then interpret the value as an Ethernet type field. Otherwise, interpret the packet as an IEEE 802.3 packet. ✨
Ethernet Numbers of Interest 💜
Many networks of every class are Ethernets (10Mb) or Experimental Ethernets (3Mb) 🍓 These systems use a message "type" field in much the same way the ARPANET uses the "link" field.

# APPENDIX A 🎀
Okay bestie, this is the number drawer 🔢✨ It's where the network numbers in class A, B, and C addresses get handed out across Research, Defense, Government (Non-Defense), and Commercial uses. Let's peek inside 👀
## Network Numbers
Class A (highest-order bit 0)
Research allocation: 8 Defense allocation: 24 Government allocation: 24 Commercial allocation: 94 Reserved Addresses: (0, 127) Total 128
Class B (highest-order bits 1-0)
Research allocation: 1024 Defense allocation: 3072 Government allocation: 3072 Commercial allocation: 12286 Reserved Addresses: (0, 16383) Total 16384
Class C (highest-order bits 1-1-0)
Research allocation: 65536 Defense allocation: 458725 Government allocation: 458725 Commercial allocation: 1572862 Reserved Addresses: (0, 2097151) Total 2097152
Class D (highest-order bits 1-1-1)
All addresses in this class are reserved for future use.
Okay so Class D is the one that's fully on hold 🙈 Every address in it is reserved for future use, so no vibes there yet 🫶
Now the Research crowd is a little more particular 🧐 Network identifiers only get granted to applicants who can show evidence that they're acquiring standard Bolt Beranek and Newman gateway software, or who have implemented or are acquiring a gateway that meets the Exterior Gateway Protocol requirements. Getting the Berkeley BSD 4.2 UNIX software might count as evidence of the latter 💻
Experimental networks that become operational don't have to be renumbered, and that's honestly so iconic 🦋 The identifiers can just move from Research to Defense, Government or Commercial status. So network identifiers can change state among those four uses, but the number allocated to each use has to stay within the limits listed above 💅 To keep that flexible, the network identifier spaces aren't split up by a simple partition. They're assigned one specific identifier at a time 🧩
## Protocol Identifiers
These assignments are shared by all four communities 🌈
## Port Numbers
These assignments are shared by all four communities 🌸
## ARPANET Link Numbers
These assignments are shared by all four communities 🛰️
## IP Version Numbers
These assignments are shared by all four communities 🔢
## TCP, IP and Telnet Option Identifiers
These assignments are shared by all four communities 🧚
## Implementation
Joyce Reynolds is the coordinator for all number assignments 👑 Slay queen, she's the one to go to 💖
