I would say the contact with support should be made by the hotmail subscriber. They can claim they don't receive their important mail and want that situation rectified. They have a customer relation with hotmail. My experience is that contacting services where you are not a customer yourself is usually very difficult and will often not result in any action. > FYI I do already have SPF, PTR and DMARC records published in DNS which > has ensured reliable delivery to gmail addresses, but hotmail seems to > have their own internal scoring system Another problem is that hotmail uses a cache for SPF and DMARC and it takes very long to expire. I have seen mail problems in hotmail at least a month after an SPF record was changed to include more valid addresses, and they were still considered invalid (resulting in postmaster report via DMARC info).

hotmail
by Brian Kantor 04 Oct '17

04 Oct '17

We're having some problems with 44net email to and from hotmail.com. Mail from that domain is getting delayed, sometimes for hours, and mail going to addresses in that domain is received by the server but not delivered to the users mailbox. I think I've fixed the delay problem by adding more IP addresses to the greylister 'whitelist', but I don't know of anything I can do about the delivery problem. - Brian

Questions on Routing Methods..
by Loren Tedford 03 Oct '17

03 Oct '17

Greetings everyone! I would like to first say that i am new to the Mailing list and this is my first email on this list.. If you wish to learn more about me and ham radio you can visit http://kc9zhv.com or http://lorentedford.com Technology wise i am involved heavily in Gaming Live Streaming and I rent a Rack Server from SoYouStart out of Canada a derivative of OVH Data Centers. I am curious if it is possible to route a /27 of ips to one single static ip from my web and email server that also handles my routing vpn services and many other things.. I use a specialized distro called Neth Server I am particularly running on Neth 6.8 for reliability reasons basically Centos or Red Hat distro.. So i suppose in closing how does everyone else route ip's around? Do you rent a server like i do and point it at the ip? I know in my Data center I have 14 dedicated public ipv4 ips to my disposal. Also will they issue a /24? If so I could use it not only in combination with my 14 Allstarlink nodes but handle some of my echolink servers and stuff as well.. Maybe put up some Echolink Proxies for others to use its not like that takes up any processing power in Linux environment.. Anyway thanks for the time 73 for now -- Loren Tedford (KC9ZHV) Phone:618-553-0806 Fax: 1-618-551-2755 Email: lorentedford(a)gmail.com Email: KC9ZHV(a)KC9ZHV.com http://www.lorentedford.com http://www.kc9zhv.com http://forum.kc9zhv.com http://hub.kc9zhv.com http://Ltcraft.net http://voipham.com *************************************************** CONFIDENTIALITY NOTICE: Confidential information, such as identifiable patient health information or business information, is subject to protection under state and federal law.

I sometimes have similar problems with gmail.com. I send replies to allocation requests to the user's gmail address and they never receive it, and become impatient and repeat the request. Sometimes I can fix it by using a different sender mail address. It looks like those big guys (who of course get billions of spam messages a day) use a lot of sender profiling and low-volume senders like @amsat.org and @*.ampr.org get low in their reputation score. So with a *.ucsd.edu sender address you had a quite higher reputation score. Mentioning IP addresses in the mail body does the rest. (often considered an indication of spam) Rob

Recursive DNS
by lleachii＠aol.com 02 Oct '17

02 Oct '17

All, The DNS servers that I copied the zones AMPR.ORG and 44.IN-ADDR.ARPA from, are no longer responding. My DNS server at 44.60.44.3 (dns-mdc.ampr.org) is still up and available for client DNS resolution; but the AMPR.ORG and 44.IN-ADDR.ARPA zones are no longer local copies. Just an FYI. If anyone else is running DNS, ensure that your AMPR.ORG and 44.IN-ADDR.ARPA zones are up-to-date. 73, - Lynwood KB3VWG

Re: [44net] Using IPv6 hosts for AMPRNET

I believe it would be too much to > expect each of the 600 or so subnet gateways to become "dual-stacked". I will certainly consider adding IPv4-over-IPv6 tunneling to our gateway for 44.137.0.0/16 when there is demand for it. We are already IPv6-connected but at the moment this is only used for out-of-band management (to prevent locking myself out of the system when doing work on the complicated IPv4 routing and firewall) Of course that would indeed mean it is not meshed over IPv6 but of course it still participates in the IPv4 mesh. When there is sufficient uptake in other parts of the world, additional meshing over IPv6 could be considered. I agree that some method, preferably an internet standard, should be used to disseminate IPv6 tunnel information. It would decrease the difficulty of adding a gateway for those that e.g. want to use surplus commercial routers. Rob

A Brief History of the AMPRNet (44.0.0.0/8)
by Brian Kantor 01 Oct '17

01 Oct '17

It's been interesting going over historical documents, RFCs, and some personal correspondence with people who were involved with the AMPRNet at various times. I think we've now got a pretty good picture of the history of the AMPRNet up to the current day. Let me recap the history as I know it: In 1981, Hank Magnuski, KA6M, got the network with a phone call to Jon Postel at USC-ISI, later the SRI-NIC. Around 1983, Hank passed it on to Phil Karn (KA9Q), then at BellCoRe. Phil managed it until he left to go to work at Qualcomm in San Diego, and gave it to Wally Linstruth (WA6JPR) [RIP 2010]. Phil is now retired, and continues to be involved with AMPRNet. Around 1988, Wally passed the network on to me to manage, and I've been doing so ever since. In 2011, it seemed wise to legally formalize the ownership, so we incorporated our organization, Amateur Radio Digital Communications (ARDC), as a non-profit 501(c)(3) tax-exempt charitable organization, and I became its president. The American Registry of Internet Numbers (ARIN) and Internet Assigned Numbers Authority (IANA), which are the authority in these matters, recognizes us (ARDC) as the legal owner of the AMPRNet, 44.0.0.0/8. If there's any corrections needed in the above brief history, please let me know. - Brian

Using IPv6 hosts for AMPRNET
by Steve Fraser 01 Oct '17

01 Oct '17

Hi All, AMPRNET consists of IPv4 addresses 44.x.x.x. Tunnels used to support AMPRNET use IPv4 hosts as destinations for the tunnels, creating a "mesh-like" network. Bent OZ6BL and I have been experimenting with using an IPv6 host to carry AMPRNET traffic. The reason you might want to do this is that IPv6 addresses, particularly static addresses, can be much more readily available than with IPv4. Also, it's an interesting thing to try! We have working tunneled 44.x.x.x connectivity between three different IPv6 hosts. However, there are some issues that arise, mainly due to the way in which AMPRNET functions. Tunneling IPv4 inside IPv6 (ip4in6) is easily done and is well documented. In Linux, commands like these are all that's needed: /sbin/ip -6 tunnel add ip6tnl1 mode ip4ip6 \ remote 2001:0DB8:112:35c::5630:6324 \ local 2001:0DB8:1245:5200::ca0c:5902 /sbin/ip link set dev ip6tnl1 up /sbin/ip route replace 44.145.40.32/32 dev ip6tnl1 src 44.136.170.20 It's very similar to how conventional AMPRNET is set up. However, the first issue is that with ip4in6 you cant (unlike ip4in4) leave the "remote" address empty, and then use routing commands to set the destination for different AMPRNET hosts (you'd be trying to add an IPv4 route to an IPv6 gateway destination). So there's a scalability problem - you'd need to set up a different tunnel device for each subnet you communicate with! The second issue is interoperability - if Alf, Bob and Charlie each only have IPv6 hosted AMPRNET, and Doug, Ed and Fred have only IPv4, then A, B, and C can communicate with themselves, as can D,E,F, but the two groups cannot interconnect from tunneled addresses. Of course, A,B and C could host IP4 tunnels as well, but that would somewhat defeat the purpose! Alternatively, one or more gateways (G) could host both IP4 and IP6 based tunnels, and route between the different type of network, a bit like this: A,B,C <----> G <----> D,E,F Could/should amprgw be configured to do this? Or maybe some hosts elsewhere do that function? But it adds complexity to the overall routing setup (and starts to become a more centralised network). The final issue is dissemination of the information - can the portal be modified to support IPv6 hosts, or do we need another mechanism? Can encap.txt be used still? Would facilities such as ampr-ripd and ripd44 need modifications? So there's plenty to think about.... Steve, VK5ASF
