Uh... Do you have Phase V installed?
Hehe - It’s VAX VMS 2.0 running DECnet 1.3 which I think is phase II based on the gunkies post at https://gunkies.org/wiki/Installing,_Configuring,_and_Testing_DECnet_V1.3_on_VMS_V2.0<https://gunkies.org/wiki/Installing,_Configuring,_and_Testing_DECnet_V1.3_on_VMS_V2.0>

Oh! Wow. Other end of spectrum. I don't remember ever touching that. Earliest VMS I ever played with was 3.7, if I remember right. Also never used Phase II. Earliest was Phase III. Did Phase II even support more than 43 nodes? I guess I should check some. :-)

43?   The spec says Phase II node numbers are in the range 2 to 240, but they aren't actuallly used for anything.  So, in a sense, Phase II can handle any size network.  But it doesn't do routing except the limited "intercept" stuff.  Still, with PyDECnet intercept, a TOPS-20 V4 node can talk to any HECnet node.
