It would work perfectly fine with a domainname like mail44.s57nk.ampr.org (both forward and reverse) and then in hamradio.si an MX record with that name. For this kind of thing we use "club callsigns" like pi9noz or pi4nos. Rob

Reverse DNS and access to DNS info
by Rob Janssen 17 Jun '20

17 Jun '20

I notice that more and more 44net traffic originates from addresses that are not registered in DNS. To identify an amateur radio transmission, it is required in most countries that the callsign is included in transmissions. Up to now I have considered traffic from a net44 address to be identified by the reverse name that can be looked up in DNS, and that has the basic structure of "hostname.callsign.ampr.org" (with of course some variations, but always the callsign of the responsible station is part of the name). I think everyone should be encouraged (or even required) to register all used addresses in DNS. There may have been some hurdles to do that in the past (e.g. the never completed DNS part of the portal, the unavoidable restrictions of the ampraddr robot to accept only updates from coordinators). Everyone who has e.g. a number of hosts in the 44.190 or other not nationally registered parts of the network can send a list of their IP addresses and corresponding hostnames (with names like the above, i.e. a callsign embedded in them) to me, then I can submit them to the robot and they get registered in the ampr.org main DNS service. Otherwise please register your hosts through your local coordinator, even when you have been allocated an entire subnet. Furthermore, I see that more and more subnets have arranged to delegate DNS to their own servers. I think it would have been better to keep everything in a single list and then run a secondary zone within the own network (we do that here), instead of this split. Maybe a more convenient API for updating the main DNS should be (or would have had to be) added to avoid this? Or are there other reasons for operating this way? Given that we now have this situation, I think there should be a general policy of allowing AXFR and preferably also IXFR zone-transfers of these zones between net44 addresses. We should not have "dark and secret" zones that are inaccessible to others, I think, especially for the reverse (PTR) zones. Rob

why and Wiki
by Dave Wade 17 Jun '20

Folks, Being marooned in that back water that is the UK I wonder what TCPIP packet activity there is in the UK and on what frequencies and how this would be supplemented by using 44net over the internet? I though I would read the Wiki but that seems to be un-availble.. Dave Wade G4UGM & EA7KAE

>I'm replying to the main thread, as Rob still insists with posting using his >broken MUA which breaks threading, making it impossible to follow his >ramblings. Thanks Rob. It is not convenient for me either! But I don't want to forward this list as separate mails as sometimes there are frantic discussions about topics that do not interest me at all (like RPKI) and I don't want my mail bell to ring all day (and load amsat.org with forwarding all those messages). So I am subscribed to the digest only, I sometimes watch the archives for quicker responses, and I cannot reply with the proper threading. I think I have mentioned it before: this list should be a newsgroup on an NNTP server. If only to honor Brian Kantor. Accessing it via a usenet news reader would be so much more convenient, you can just read it when you like and kill uninteresting threads. Or otherwise just use a forum. >Having reverse DNS with a callsign in it doesn't meet identification >requirements in the ITU or FCC rules, assuming the packet is traversing an RF >link on amateur frequencies. Under FCC rules (and I'm aware you may be under >a different legal authority), the control operator is the required ID, not the >originator of the packet. It is not only about regulatory ID requirements but also about identifying who is behind some traffic. Many places have "relaxed firewall rules" for traffic originating from within AMPRnet. This already requires revision due to the sale of the upper block (I think that lots of firewall rules still mention 44.0.0.0/8) but also with more and more blocks being routed directly and having no transparency about the actual use of that space, I would like to know if some address is really an amateur or if someone has lend it out to shodan.io or stretchoid.com. And if so, at least know who is responsible for that. When that is not feasible, we will have to become more and more closed and more like the general internet (default drop everything). Rob

>I am not sure what you mean by feared, but no, my allocations are not supporting the AMPRnet per se. If by AMPRnet you mean the legacy BBS style network of gateways and tunnels. I don't. With AMPRnet I mean what is described on the ARDC pages, not a set of applications and an old way to implement tunnels. So, the net44 address space and its use for amateur radio communications. Use for IRLP would be part of that. But in that case it should be possible to have reverse entries pointing to the callsigns involved. Rob

>The reason I did this was because I needed PTR records in something other than ampr.org. I already feared that it was to conceal non-AMPRnet usage... This makes it all the more important to have zone transfer capability so the data can be used to validate against local policies. Rob

I have that fully working using a collection of scripts, but indeed it would be convenient when there was an easier and more modern API for it. As it is now, you can download the zonefiles from an FTP server (or of course you can do lookups at the master server ampr.org at 44.0.0.1) and compile a list of updates (using diff between the downloaded- and the desired info) and then you can create an e-mail message to the ampraddr robot that will do the updates. For this to work you have to have your mail sender address whitelisted. (it used to be an open service until it was abused) Rob

VK AMPR Co-ordinator
by Gary B 13 Jun '20

13 Jun '20

Hi All, For info for those who knew Sam Scafe, VK4AA, who was the Australian AMPRnet Co-ordinator. SILENT KEY: - Samantha Scafe VK4AA Samantha went Silent Key on Saturday March 22nd at home in Cairns following complications from cellulitis interacting with a compromised respiratory system. Samantha had recently been in hospital a number of times but appeared to be improving before her health took a final dive. Samantha was one of the pioneers of Packet Radio networking in Queensland being one of the first to introduce the concept of data wormholes with the Aussie Wide Packet Radio Network. A move from the Gold Coast to Cairns found Samantha’s business become a ISP and Web Host/Design concern, including providing the backup site for the WIA News and QNEWS data files. Samantha and partner Colleen were also well known in autosports circles as CAMS Stewards, with many RadioAmateurs interacting with them at rallies and hillclimbs. Samantha also ran the Cairns APRS gateway for years and provided technical support for repeater builders around the country. The Australian Amateur Radio Service has suffered a great loss with Samantha’s passing and we pass on heartfelt condolences to partner Colleen and family. Vale Samantha Scafe VK4AA, Silent Key. >From Backscatter (Newsletter of the Townsville Amateur Radio Club) As a result, VK needs someone with AMPRnet and TCP/IP kwowledge and experience to volunteer to take on this role. If you think you are able to do this, or know someone who possibly could, please contact Chris, G1FEF asap. Currently VK does not have anyone to do the day to day co-ordination or issuance of 44. addresses. Regards, Gary VK4ZGB
