the Internet?

majority of the internal network was vm370 ... since MVS/JES2 nodes had
to be relegated to mostly boundary nodes ... JES2 was unable to define
the complete network and had unpleasant characteristic of discarding
traffic if the origin &/or destination node wasn't in its local table.
Also JES2 had periodic characteristic of crashing MVS ... when it
received traffic that originated at JES2 at didn't release level (in
fact, there was large library of VNET NJI drivers to talk to JES2 that
specifically reformate traffic originating at other JES2 nodes to try
and prevent MVS systems from crashing). also mentioned in this
recent post

references:

On p. 13 of The REXX Language by M.F. Cowlishaw, there's a reference to
how the development was done.  "IBM has an internal network, known as
VNET, that links over 1600 mainframe computers in 45 countries."
That book is dated 1985.

... but 1600 count would have been when book was written & before
actual publication date.

this old post
http://www.garlic.com/~lynn/2002k.html#26 DEC eNet: was Vnet : Unbelievable.

has this statistic

BITNET    435
ARPAnet  1155
CSnet     104 (excluding ARPAnet overlap)
VNET     1650
EasyNet  4200
UUCP     6000
USENET   1150 (excluding UUCP nodes)

... snip ...

also from sometime in 1985 (up from 1000 nodes in 1983). But there are
also references by end of 1985 there was 2000 nodes on the internal
network ... referenced in this old email
http://www.garlic.com/~lynn/2006t.html#email850625

However, the arpanet/internet was rapidly increasing and sometime either
late '85 or early '86 passed the internal network in number of network
nodes. post containing the 25Jun85 email
http://www.garlic.com/~lynn/2006t.html#50 The Future of CPUs: What's After 
Multi-Core?

references 435 BITNET nodes on 18Jan1985, 1155 arpanet nodes 22Jan1985
and by 1988 there were 2691 nodes (BITNET/NETNORTH/EARN).

Big boost for arpanet/internet growth was switch-over to internetworking
protocol on 1jan1983 (and off the IMP-based arpanet ... approx. only 100
IMPs and 255 hosts on 1jan1983).

The other factor in internet exceeding size of internal network ...  was
the communication group trying to preserve its dumb terminal oriented
paradigm ... with the internal network being restricted to mainframe
hosts ... while the internet nodes were starting to include a growing
number of workstation and PC nodes. there were numerous efforts by
communication group to protect their dumb terminal paradigm and install
base ... also discussed
