The first few requests I received for 44 net addresses came
from MSYS BBS operators wanting an IP address. In every
case, it was a very short time before they asked for another
address or two. Eventually, when I got requests regardless
from who or why, I just assigned a block of 4 addresses, then 8.
The addresses naturally fell on boundaries that could be segregated
by a netmask. They became de facto subnets. I made it clear
that was not the purpose but merely convenient for both of us.
The node operators of Netrom nodes were continually installing
TheNET X1J and instituting subnets for IP routing. Basically, the
hardware or software was driving the implementation of the
network. Not the other way around.
As I understand it, the intent was to develop a network with
enough sophistication that mobile stations (IP addresses) could
remain connected because the network would dynamically
discover and track/route without having the operator consciously
change IP address or any other identifier. RSPF is one effort
toward that goal.

I am puzzled that we want to assign 44-net

in amprhosts rather than as subnets. Perhaps there is a historical
reason for that. The routing table could get to be very large (we can hope!)
I
think the reason we started it that way was the sparse population of
addresses and the fact we coordinators didn't initially know any
better coupled with the geographical/topological distribution of IP
nodes where we couldn't really count on a node being in any specific
location within the net. Nodes had to determine their neighbors by
discovery and they were routed manually.
I didn't start subnetting until users wanted blocks of IP addresses
for specific purposes, like UHF vs VHF gateways, digipeaters, or
ARES/RACES. I wrote a paper on it but I don't know how widely it was
distributed or how well it was received.
