Thank you for the kind words David!
The U.S. DoD owns 13 /8 networks and according to a blog post in an IPv4 broker (
https://ipv4.global/blog/u-s-department-of-defense-ipv4-address-space/
<https://ipv4.global/blog/u-s-department-of-defense-ipv4-address-space/> ) they want
to sell it all off by 2030 or something like that, as they’re going IPv6-only. That’s >
213M IPv4 addresses and I personally think that if it were to enter the market, it could
cause more supply than demand. I don’t know whether or not they’ll actually do it but it’s
about as many addresses entering the market as the current amount that changes hands in
7-8 years.
I think that focusing on IPv6 and IPv6-only networks is the right path forward, and if you
see the IPv6 map of the blog post, we are giving out IP space “wastefully” and we still
haven’t even allocated a /10 out of the /0 (or more accurately the unicast /3). I would
really like to see more and better IPv6 support in modern tools, especially in ham radio,
with the goal of having them work fine in an IPv6-only environment (even with NAT64).
Maybe people want to work on OSS software and improve its IPv6 situation and apply for
grants from ARDC to do so? I don’t speak for the GAC/TAC/Board but personally I think it
would be a good idea that could benefit the entire Internet.

Hello Antonis,
Wow.. what an excellent read and the results are very interesting!
Whenever I see maps like this, I ask myself why do companies like Hp, Ford and the US
Government continue to keep such huge swaths of address space that's unused. I'm
99% sure they could sell or even give away huge chunks of address space and never notice.
One could argue that unless address block owners cannot demonstrate some level of real
usage, they should be forced to release the blocks to communities that will. I doubt that
will happen now that we really have commercially viable IPv6 but one can still wish.

Hello fellow 44net users,
Yesterday I posted an analysis of the utilization of 44/8 on my blog, and you can find
that here: https://blog.daknob.net/mapping-44net/
<https://blog.daknob.net/mapping-44net/>
I thought you may find it interesting to read, and it also includes a map of the entire
IPv4 and IPv6 Internet as a bonus so you can compare our usage to other parts of it.
A note is that currently Germany's 44.148/15 already has very similar utilization to
that of one of the most dense networks, 185/8 (comparison with 185.148/15):

<https://blog.daknob.net/content/images/2021/05/44-de-185-eu.png> . According to the
ping data, HAMNET accounts for over 75% of the hosts alive during the measurement, so
that's a great example of what is possible for the entire network!
I'll be happy to hear any thoughts and comments you may have on the topic.
