RFC 597
Host status
Host Status ✨
Title block tea: this RFC is by N. Neigus and J. Feinler, numbered 597 (NIC 20826), dated 12 December 1973, and filed under the Network Working Group. It doesn't list a category, and it doesn't say it obsoletes or updates anything 🧚
Okay bestie, so the vibe is "here are the newest network maps, geographic and logical, plus a list of every Host on the ARPANET" 🗺️✨ The geographic map shows every IMP and TIP currently installed in the subnetwork 💖
The logical map shows where every computer on the net stood as of Dec. 10, 1973 🦋 The one exception is MIT-MULTICS, which is shown in the middle of being hooked up to IMP #44 instead of IMP #5. Sorry I didn't reprint the map, I know 🙈
Here's how to read it: Hosts with interfaces to the subnet are drawn as intersected ovals 💅 A tiny "v" is a Very Distant Host (VDH) interface to the IMP. IMPs are the solid black circles, and TIPs are circles with a "T" inside. The two jagged lines are satellite links 🛰️
Heads up: the names on the map are unofficial IMP names, not official Host names. Don't mix them up 💀
The Host list has current sites plus the ones projected to join within the next two months 🌸 At the end there's an incomplete list of installations coming later. Connection dates only cover the next few months, so nobody gets a wildly wrong idea 🫶
Some quick notes before you dive in 🎀
- The Host's network address is in octal and decimal.
- The interfaces from the subnet to each computer are in parentheses, and you can totally ignore them 💜
- A site counts as a Server or User based on self-proclamation 👑
- A Limited Server performs service functions, but only for a restricted group of users. A dedicated Server means the type of service is restricted, not the group of users 😭
- In every case, normal site access restrictions still apply 🔥
- The status column also lists any special operating system on that Host that the computer manufacturer didn't supply 🍓
This RFC has the official Host names as of December 1973 ✨ The naming conventions and the official Hostname list will be kept at the NIC by Jake Feinler (FEINLER@NIC), and they'll be published in the ARPANEWS 📰 A copy of the list will be online at the NIC, and the location will be announced along with the official list. Other sites are encouraged to keep their own copies too 🧚 And a printed version will come out now and then as part of the Resource Notebook 📓
