RFC 900
Assigned Numbers
RFC 900: Assigned Numbers ✨
okay bestie, this is the big master list of numbers 💖 It's a Network Working Group Request for Comments from June 1984, written by J. Reynolds and J. Postel of ISI 🎀. The numbers in here are what keep protocols talking to each other, so it's basically the rulebook for who gets which number 💅
Here's the title-block tea 🫖:

Status of this Memo 💅
This memo is an official status report on the numbers used in protocols in the ARPA-Internet community 🦋
Introduction 🌈
Okay so this RFC is a Network Working Group Request for Comments that lists the values currently assigned from several different series of numbers used in network protocol implementations 🍓 It's going to get updated every so often, but you can always get the current info from Joyce Reynolds, who also handles number assignments 🫶
If you're building a protocol or application that needs a link, socket, port, protocol, network number, etc., you have to reach out to Joyce to get a number assigned 💖 No freelancing, bestie 🙈

ARPA mail: JKREYNOLDS@USC-ISIF.ARPAMost of the protocols mentioned here are documented in the RFC series of notes 📜 The more popular ones are in the "Internet Protocol Transition Workbook" [31] or the old "ARPANET Protocol Handbook" [32] that the NIC put together. Some of the items listed are undocumented, which is giving mystery ✨ More info on protocols can be found in the memo "Official Protocols" [83] 🔥
In every case, the name and mailbox of the person responsible is listed. In the lists below, a bracketed entry at the right-hand margin, like [31,iii], is a reference for the protocol. The number is the document and the "iii" is the person. Whenever possible, that "iii" is a NIC Ident 🧚
ASSIGNED NETWORK NUMBERS 🎀
The network numbers here are used as internet addresses by the Internet Protocol (IP) [31,71] 💜 IP uses a 32-bit address field and splits it into a network part and a "rest" or local address part. There are 3 forms, or classes 🌟
The first type, class A, has a 7-bit network number and a 24-bit local address. The highest-order bit is set to 0. That gives you 128 class A networks 👑
1 2 3
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, class B, has a 14-bit network number and a 16-bit local address. The two highest-order bits are set to 1-0. That gives you 16,384 class B networks 🦋
1 2 3
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
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
|1 0| NETWORK | Local Address |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
Class B AddressThe third type, class C, has a 21-bit network number and an 8-bit local address. The three highest-order bits are set to 1-1-0. That gives you 2,097,152 class C networks 🌸
1 2 3
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
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
|1 1 0| NETWORK | Local Address |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
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 🙅♀️
One popular way to write internet host addresses is to split the 32-bit address into four 8-bit fields and write each field as a decimal number, 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 listings of assigned network numbers use dotted decimal notation. Class A networks show up as nnn.rrr.rrr.rrr, class B networks as nnn.nnn.rrr.rrr, and class C networks as nnn.nnn.nnn.rrr. In those, 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, and each gets a one-character code to the left of the network number ✨
- Research:
R🔬 - Defense:
D🛡️ - Government (Non-Defense):
G🏛️ - Commercial:
C💼
(See Appendix A for more details on how this split works 📖)
Network numbers are assigned to networks connected to the ARPA-Internet and the DDN-Internet, and to independent networks that use IP family protocols (these are usually commercial) 💅 Independent networks are marked with an asterisk in front of the number 🌟
Administrators of independent networks must apply separately for permission to interconnect 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 assigned network numbers change for various reasons. To make the switch smoother, the old number stays listed for a transition period 🦋 Those "old number" entries get a T after the number and before the name, and the network name gets a -TEMP suffix 🧚

Okay this one is so cute. In the Internet Protocol (IP) [31,71] there's a field that tells you which version of the internetwork general protocol you're using. It's only 4 bits, so it's tiny but mighty ✨

Next up is the Protocol field. In the Internet Protocol (IP) [31,71] there's a field called Protocol that says which next level protocol is riding along inside the packet. It's an 8 bit field, so there's a lot of room for protocols to show up and slay 👑 (the original has "the the" in one spot, so I'm keeping that exactly as written 🙈)

255 Reserved [JBP]Assigned Port Numbers 🎀
Ports are the best part, ngl. Ports are used in the TCP [31,72] to name the ends of logical connections that carry long term conversations. To help unknown callers, there's a service contact port, and this list says which port the server process uses as its contact port. That contact port is sometimes called the "well-known port" 🌸
To the extent possible, these same port assignments are also used with the UDP [31,70] 🦋
The assigned ports only use a small slice of the possible port numbers. Every assigned port has all except the low order eight bits cleared to zero, and those low order eight bits are the part that's specified here ✨

ASSIGNED ARPANET LOGICAL ADDRESSES ✨
Okay so the ARPANET has this thing called "logical addressing," and you can read all about it in RFC 878 [49] 🧚 Some of the possible logical addresses are set aside for standard uses, so no random host gets to grab them 🙈
There are 49,152 possible logical host addresses in total. Out of those, 256 are reserved for well-known functions, and Joyce Reynolds handles those assignments. Everything else gets assigned by the NIC 🦋

256 Reserved [JBP]ASSIGNED ARPANET LINK NUMBERS 🎀
Okay so "link" in this section is a field from the original ARPANET Host/IMP interface leader. It started out as an 8-bit field, and then later specs redefined it as a 12-bit "message-id" field. Now when people say "link," they mean the high-order 8 bits of that 12-bit message-id 💅 The whole Host/IMP interface is defined in BBN Report 1822 [7], so that's where you go if you want the full tea ☕
The low-order 4 bits of the message-id are called the sub-link. Unless a particular protocol explicitly says otherwise, the sub-link doesn't mean anything going from sender to receiver. The sender can use it however they like, since the destination IMP sends it back in the RFNM, but the receiver should ignore it 🫶

bestie, all addresses in this class are reserved for future use 🔒
in the Research crowd, network identifiers only go to applicants who can show they're acquiring standard Bolt Beranek and Newman gateway software, or 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 later become operational need not be renumbered 🦋 instead, the identifiers can be moved from Research to Defense, Government or Commercial status. so network identifiers may change state among Research, Defense, Government and Commercial, but the number of identifiers allocated to each use must remain within the limits indicated above. to make this fluid assignment possible, the network identifier spaces are not allocated by simple partition, but rather by specific assignment ✨
