This sounds like it was a bad idea back then and a bad idea now. :)

Does anyone know what the largest DECnet deplayment was
duing the good old days?
The internal net at DEC was seriously out of addresses,
though just
like IP that's partly because the addressing scheme forced
it to be
somewhat sparse. Still, there were certainly tens of thousands of
nodes on it.

And let's not forget the hidden areas that DEC was forced to go
to...
Hidden areas? ;)
When DEC began to run out of node names/addresses (64512) they resorted
to something called hidden areas. "Spitbrook Rd" (Nashua, NH) had nodes
that were in areas 61-63 that could not be seen beyond that facility.
Other sites, like the "The Mill" and "Parker Street" (Maynard, MA) also
reused those same addresses just not the node names. If the node you
were on was in a hidden area then you had to do your own "routing" of
sorts to get the areas outside your facility.
As an example: If I was on node FOO::, and FOO:: was in a hidden area,
and I wanted to send email to another site on node BAR:: then the DECnet
path might look something like this:
ROUTR1::BAR::<username>. Where ROUTR1:: is a non-hidden area node
within my facility.
If the other end had the same issue then the chosen path might look
something like:
ROUTR2::FOO::DAVIDSON. Where ROUTR2:: is a non-hidden area node within
the source facility.
This was referred to as PMR (Poor Mans Routing). The concept was not
new because it had been used in previous versions of DECnet anyway, the
application was... Sort of... HECnet has reserved area 63 for hidden
area nodes - to play with mostly. I did some playing around last year.
If I can ever find my notes (from DEC days) about the whole setup I will

My DTC01s and DTC03s can *speak" many many different things too! ;)

Although, the guts of the Internet DEC engineering network was a Class A (net 16) address and it was IP routed and IP managed and DECnet hung off of it once it got an extreme size and scale.
