Hi Benoit,
44/8 is announced via UCSD indeed. Within that /8 there is a /16 per country, which each country may announce, if requested. Each /16 is subdivided in user networks, those are managed by the country coordinators. Users may announce their own subnet (starting from a /24) via BGP if they request it and fill in the document as requested by Brian Kantor.
A country may decide to advertise their /16 to the internet, or they can choose to not advertise it, and only use it as an "internal" range If your /16 is announced by your countries coordinators, then you should go and see them and request how your network can be routed to and from the internet. If your coordinators choose to not announce it, it will be reachable via the /8 that is announced at UCSD, but only if your ip's have a valid reverse DNS configured. Those DNS entries can either be added by your countries coordinators, or by Brian.
From what I see in the global internet routing table, your IP country does not advertise it's /16, but your IP goes via AS7377
I hope this clarifies some things for you.

Dear List
I'm pretty newly connected to hamnet, and also work at an ISP.
I always assumed 44.0.0.0/8 would not be announced to the internet, but only routed privately on hamnet.
Now I see routing issues I don't quite understand as for me this looks like routing is completely broken...
On the internet core router I see that 44.0.0.0/8 is being announced by AS7377 (UCSD).
But IP Addresses from the swiss HamNet range are not reachable via AS7377. So what is the point announcing the whole range to the internet? There is no 'more specific' route to 44.142.200.1
On the other hand I cannot reach parts of hamnet via hamnet. Take for example the Primary DNS of ampr.org:
ampr.org. 3600 IN SOA ampr.org.
ampr.org has address 44.0.0.1
1 gateway (157.161.57.65) 2.947 ms 2.887 ms 2.847 ms 2 mikrotik-hamnet.woody.ch (192.168.57.243) 4.937 ms 4.920 ms 4.887 ms 3 rf0.am-32.hb9am.ch.ampr.org (44.142.162.97) 21.810 ms 24.858 ms 29.860 ms 4 bb-hb9am-30.db0wbd.ch.ampr.org (44.224.90.81) 29.847 ms 32.792 ms 32.771 ms 5 wan-db0wbd.hc.r1.ampr.org (44.148.240.45) 78.907 ms 81.925 ms 84.438 ms 6 dc1-dc2.hc.r1.ampr.org (44.148.255.253) 97.808 ms 98.107 ms 113.973 ms 7 wan-db0gw.db0fhn.ch.ampr.org (44.224.122.2) 113.986 ms 113.149 ms 118.384 ms 8 db0fhn.ch.ampr.org (44.130.60.100) 126.890 ms 118.628 ms 137.776 ms 9 * * *
My Gateway has a default route to the internet and a static route for 44.0.0.0/8 pointing to my WLAN Link to a 'public' Hamnet AP.
So what is the point of having sort of a split-brain situation on the 44.0.0.0/8 hamnet ip range?
I 'see' ospf packets on the WLAN link, but they only seem announce the local routes withing the swiss part of hamnet, not the global routes. Sort of makes sense, as you probably would run bgp to interconnect the different hamnet as numbers.
So do I need to get an own hamnet as number? As a User?!?
Or what mechanism is there supposed to be to tell a user which hamnet ip ranges are reachable via internet and which ones are reachable via hamnet.
