The internet report named after an office room

A closer look

The foundational rulebook for how early internet nodes talked to each other was creatively named after a random office door. When building the ARPANET, engineers had to figure out how host computers would interface with Interface Message Processors (early routers). The resulting spec, the BBN Report 1822, laid the absolute groundwork for packet switching and network communication. They didn't give it a flashy acronym or a sci-fi moniker. They literally just named the most important document in early network archaeology after the room number where they happened to be sitting.
