Hi Rob, and thank you for your answer.

But you can be the volunteer yourself!
That was my first approach, one year ago. As Corsica is a "separate"
country in terms of ham radio, I first thought about asking for a
dedicated subnet, and become the local coordinator for our island. I
just received flames via private mails that had nothing to deal with
technical arguments and hamradio. That made me stay with private
addressing, which suits our needs. The only current drawback is the
management of D-Star, DMR, XLX and other digital stuff, which require
hacks such as dual adressing, NAT and so on.
But, after talking with DL5NGN and F6CNB, who operate big networks in
Europe and France, I was told to forget NAT and private addresses, and
to use hamnet addressing. Following their advice, I arranged a /23
subnet (44.168.80.0/23) with the coordinator. I'm now waiting for
validation.
We all know about the difficulty in getting IPv4 space on internet,
but using Net-44
space for a Wireless ISP that just happens to have a couple of radio
amateurs in
its admin team is not the way to go.
So you will have to present convincing evidence that this is not what
is going on.
We have two skilled network engineers, two data centers in the two main
cities of the island, with plenty of free space, free transit over the
public fiber backbone, free public IPs, BGP capabilities, access to high
points, and free second hand hardware such as switches, Cisco routers,
hp Proliant DL servers with RAID controllers, and many other things. And
we have plenty of (unfortunalely, not hundreds of) HAM guys involved in
repeaters, digital, contesting, remote station, etc... who are just
waiting for extension of the IP backbone to their location.
I think many regions of the world don't have so much. Even the region of
Paris does not actually have BGP capabilities (we are working together
to share our data centers and informations for redundancy).
We already built the most important elements of our network with private
addressing, and it works. We also have a lot of projects. We could just
deploy sites with our current techniques (OpenWRT / OpenVPN) with
private addressing. But, as said before, several skilled people in
Europe convinced us to switch to hamnet addessing. That's what we are
trying to do. Our current net is still working on private addressing,
and we already started building a lab on separated VMs for hamnet
addressing, firewalling, and BGP over our two data centers. We are now
waiting for IPs...
This way I don't have to worry about providing DNS
service on internet
(which is a
can of worms...) and still everyone has access to our names. Reverse
also works,
which is usually a problem on the independent networks.
We'll investigate that. I'd like to avoid opening DNS directly to
Internet, even through firewalls and secure gateways.
