This is easily fixable at the pop level. Still no need for complicated setups.
Since every subnet has to he known in the portal, a script could parse the portal for all
known subnets and only allow those in and block the unknown subnets.
Again, no need for complicated routers/routing.
At the edge level you allow 44/9 & 44.128/10 and the pop filters the rest so that bgp
hijacked subnets cannot even get to the network, let alone your edge
There’s a simple answer to all cases that does not need renumbering.
We also cannot have a part of the network not reachable for other hams and cannot ask
every ham to have 2 subnets and do complex routing themselves.
Amprnet is an open network for hams and everything should be easily reachable to all hams
that connect to amprnet.

Well as I said to Ruben this is wrong.
You may think you will fix the problem with such simple fix.
The networking world is not as "clean" as you think. Once someone advertise a
subnet in the 44.0/09 or 44.128/10 they would have access to your network. The thing is
that it is already happening and AMPR/ARDC are already monitoring such event but it take
times to find those rogue people, then AMPR need to contact the owner of the network that
provide the bgp route top the rogue guys. Those could be legit guys but are with the rogue
group and they could delay for days if not weeks the action needed to secure back YOUR
network. Do you want to leave the front door of your house to the public if you were made
promises that no one but the legit owner of the neighbourhood would have access to the
road in front of your house? Not the same security risk I think.

I agree! That motivation to split the network is totally bogus.
Everyone in 44.0.0.0/9 and 44.128.0.0/10 can be "trusted" to be radio amateurs,
it does not matter if they
are on an isolated network or on a network connected to the internet.
How it is routed (over radio or over internet tunnels, using what routing protocol, and
what policy,
does not matter at all.
Of course on an isolated network you can have bad guys as well, so you will always have
to be
careful what you open up to others.

Dual addressing means complicated policy based routing.
The remaining 44net that we have today is ham only. Thus if one does not the internet to
reach his/her subnet, all they have to do is add a simple firewall rule allowing 44/8 and
44.128/10 and denying the rest. That is a lot easier than policy based routing or dual
addressing. That would allow fellow hams to reach the subnet, but not the rest of “the big
bad internet”
