Hello,
as far as I know, 44.128.0.0/16 is reserved for testing and experimentation and should be
treated much like an RFC1918 subnet. That means it will not be routable to anyone
(although it is advertised on BGP). So I have a few questions about its use:
1. Can an AMPRNet member use 44.128.0.0/16 in their home instead of, let’s say,
192.168.1.0/24? Note that I am not talking about routing these addresses, just use them in
a non-connected place.
2. Can a non-ham use 44.128.0.0/16 in their home instead of, let’s say, 192.168.1.0/24?
3. Can a company use 44.128.0.0/16 for their intranet, instead of, let’s say, 10.0.0.0/8?
Note than in all three cases, nobody is connected to 44net gateways and just use the
network like any other private address. I am aware that there’s no technical limitation in
doing this and there are hardly any benefits from doing this, however I am asking for
informational purposes.
Thanks!

Although it would, at this moment, not have any significant effect
on the operation of the network if someone used it and it leaked out,
I feel it would be wise to avoid using it at all for anything
permanent or semi-permanent, as some day we may decide to assign
it somewhere and start routing it.
Some years ago a large router company used 44.x.x.x addresses as
examples in their documentation. As one might expect, some people
used them right out of the examples and they leaked. It's always
wise not to trust every single router configuration to get things
right, and it would only take one to complicate things.
So my advice is to avoid using 44.128.x.x for anything other than
really short tests. There are plenty of non-routed RFC1918 addresses
and subnets available and they are much less likely to get propagated
anywhere if they leak.

I seem to recall 44.x.x.x being used at large trade shows 20 years ago or
so....

This network is used by NASDAQ for their test network. I constantly ran
into it when I worked on Wall Street. I've reported this before but it
always goes nowhere.

Yes, people even used 5.0.0.0/8 like RFC1918 space before. No one can dictate
what space you use in your own private network.
Is it a good idea? no.
