The list of TCP and UDP port numbers [1] is a treasure trove of historical artefacts. It's amazingly hard to find information on e.g. "compressnet", which is wasting port 2 and port 3 for eternity.

Available also at /etc/services or %SystemDrive%\%SystemRoot%\System32\drivers\etc\services id Software's Doom having port 666 (unofficially) assigned is a nice touch.

  Another similar trivia is present in PCI-IDs. Intel got 8086 for themselves. Some other notable examples: Broadcom/LSI: 1000 Motorola: c0de Chrysalis-ITS: cafe Blackmagic bdbd Indigita Corporation dead Middle Digital Inc. deaf Elcus e1c5 Eagle Tech ea01 Essence Tech e55e Echo ecc0 Daiblo Tech db10 Canny Edge caed CACE Tech cace There are many more examples, but it's enough, I think.

  I was skeptical at first but found evidence to corroborate it's the same thing, the key fact being the company named Process Software. The reference in RFC1340 for it says "Bernie Volz" of process.com. Searching on that let me to a Web-0.9 style page with the text "compressnet/tcp is a protocol that is used to compress TCP connections for WANS. It used two ports to compress tcp conections, one to send the compressed TCP connection data through, and one used for the management of CompressNet. This is a commercial product only." https://donsnotes.com/tech/networks/internet/proto/compressnet.html https://donsnotes.com/tech/networks/internet/proto/compressn...
