I'm still running real hardware. PONDUS is a 11/93 that is running 24/7.
But no, I doubt one server would even get close to simulate all ever
existing DECnet machines. But it could be an interesting exercise to try
and figure out how many machines you'd need.
DEC's internal DECnet (Easynet) was definitely going over 50.000
machines (I actually don't know how big it was at its maximum). And that
in the 80s. Then you get all the Alphas and Itaniums that came later. If
you want to emulate them, you'll get challenged for CPU and network
resources pretty quickly.
I migrated some PDP-11 systems away from DECnet to TCP/IP that was
running testing things at Saab around 2005. And that was because they
were shutting down DECnet in their facilities, but they wasn't getting
rid of the PDP-11s at that point in time. Who knows how many sites
use/used PDP-11s and DECnet around the world. I know of at least one
place where I know they were still running VAXen and PDP-11s with DECnet
in production as late as last year. I strongly suspect they are still
running their stuff.

there still has real hardware connected to HECnet however. I do
occasionally, at least for now.
Speaking of which, I notice that IAD2 59.1020, has not connected to
the new A2RTR. STUPI and STORTR have, however. Is there a problem
with IAD2?
And speaking of networks, what happened to your ANF10 connections?
I’m still running the PDP10 simh on my home machine, so those IP
addresses have not changed. Don’t know if you were using
decnet.jfcl.com for those connections, but if you were then you can’t
anymore. I suppose I could create an anf10.jfcl.com for this purpose…
Hang on, I’ll go do that now…
Ok, done – I just added an anf10.jfcl.com for this purpose.

If we put all routers and all emulated machines in the Amazon cloud,
the who HECnet can live in one VM...
