Tom, The solution is easy, just have a dual-stack MX record. $ host gmail-smtp-in.l.google.com. gmail-smtp-in.l.google.com has address 172.253.115.26 gmail-smtp-in.l.google.com has IPv6 address 2607:f8b0:4004:c06::1a Servers using IPv6 connect to IPv6 as needed.

Anyone have contacts at the Amazon or OpenAI web spiders?
by John Levine 14 Feb '24

14 Feb '24

One day I set up the world's lamest content farm. You can see it here: https://www.web.sp.am/ While humans tend not to find its six billion pages very interesting, some web spiders are entranced. In the past week or so, Amazon's amazonbot has visited it 6 million times, and OpenAI's gptbot 2.6 million. (If you were wondering what they use to train ChatGPT, now you know.) I don't care that googlebot comes by every 5 or 10 minutes, but gptbot is every few seconds and amazon as fast as the server will respond. They both come from predictable IPs so I can set packet filters but they're still hammering pretty hard. Each has a URL in the user agent string, Amazon's page has an address to write to but OpenAI's doesn't. I wrote to the Amazon address, no response. If anyone has contacts at either I would appreciate it. A few years ago the bingbot got trapped but fortunately I knew someone at Microsoft who could pass the word. He reported back that while he could not go into detail, there was a great deal of animated conversation at the other end of the hall, and shortly after that it stopped. R's, John

route: 0.0.0.0/32 in LEVEL3 IRR
by Frank Habicht 14 Feb '24

14 Feb '24

Hi, I got 2 bounces for the email addresses seen below for an email similar to the below... Anyone want to remove this IRR entry before anyone notices...??? ;-) Frank I believe that the entry of route: 0.0.0.0/32 does not serve any good purpose? I was surprised to see it in a list of prefixes from bgpq4 and the very good https://irrexplorer.nlnog.net/prefix/0.0.0.0 guided me that it's in "Level3". I'm wondering how many auto-generated filters contain this unnecessary prefix.... PS: Oh, just seen - it's from TODAY. Maybe remove before anyone sees it...? Thanks for looking into this, Frank [frank@fisi ~]$ whois -h rr.level3.com 0.0.0.0/32 [Querying rr.level3.com] [rr.level3.com] route: 0.0.0.0/32 origin: AS10753 mnt-by: TCCGlobalNV-MNT changed: ankita.grewal(a)lumen.com source: LEVEL3 last-modified: 2024-01-30T11:04:49Z [frank@fisi ~]$ whois -h rr.level3.com TCCGlobalNV-MNT [Querying rr.level3.com] [rr.level3.com] mntner: TCCGlobalNV-MNT descr: TCC Global N.V. auth: CRYPT-PW DummyValue # Filtered for security upd-to: ripehostmaster(a)eu.centurylink.net tech-c: LTHM admin-c: LTHM mnt-by: TCCGlobalNV-MNT changed: ankita.grewal(a)lumen.com source: LEVEL3 last-modified: 2024-01-30T11:01:52Z

Any AI or Data Science Projects?
by Adrian Bolster 13 Feb '24

13 Feb '24

Hi everyone, I am a masters student of Artificial Intelligence and Data Science at the University of Hull and I am in need of a suitable project for my final semester. Prior to studying I was heavily involved in the formation and building of an ISP network in my local area. We built out to approximately 15k customers using a mix of wireless and fibre before selling the business to a competitor in 2022. I am still very interested in all things Internet and would very much like a project within this sector. If anyone has any requirements or any ideas then please do not hesitate to contact me off list. Many thanks, Adrian. Sent from my iPhone

IRRD & exceptions to RPKI-filtering
by Job Snijders 13 Feb '24

13 Feb '24

Dear all, At NANOG 90, Merit presented on their IRRd v4 deployment. At the microphone Geoff Huston raised a comment which I interpreted as: "Can an exception be made for my research prefixes?" There are two sides to this: INSERTING RPKI-invalid route/route6 objects =========================================== By default, IRRd v4 rejects submitted route/route6 objects if the system detects the objects to be RPKI-invalid. This helps guard against typos, mistakes, and some forms of adversarial actions. However, some researchers find this protection annoying, because the 'noise filtering' mechanism interfers with their ability to insert noise to measure noise. ;-) In order to allow users to insert RPKI-invalid route/route6 objects into the database, the IRRD operator needs to make use of a so-called SLURM file. SLURM is an IETF-standardized JSON format to describe 'rules' to be applied to RPKI-derived information passing through a pipeline. RADB would need to adjust their configuration to point to a SLURM, and add the prefixes of researchers to the 'prefixFilter' section. https://irrd.readthedocs.io/en/stable/admins/rpki/#slurm-support Of course, RADB (or any IRRd v4 operator) will need to vet whether the researchers actually have some authority to make requests on behalf of the Resource Holder! I wouldn't like it if some random person could ask for ROAs related to my employer to be ignored! :-) It is up to each IRRD operator as to what their policy is on assisting researchers and making exceptions to the RPKI-filtering mechanism. QUERYING for RPKI-invalid route/route6 objects ============================================== By default, IRRd v4 returns RPKI-filter responses for WHOIS queries related to routes. This is done to help safe guard the ecosystem. Users can disable filtering of objects by issuing '!fno-rpki-filter' in the WHOIS connection. This is intended as a debugging aid. See this page for more information on the various WHOIS queries that IRRD v4 supports: https://irrd.readthedocs.io/en/stable/users/queries/whois/ Kind regards, Job

IPv6 Test Pages for Fortune 500 and Top 100 web sites are back
by Owen DeLong 12 Feb '24

12 Feb '24

Don’t know how much anyone will still care about these pages as there are lots of other sources of similar data these days. However, I finally got around to fixing the two pages I maintain: http://www.delong.com/ipv6_fortune500.html and http://www.delong.com/ipv6_alexa500.html In the case of Alexa, the page is no longer based on Alexa since Amazon discontinued that service and now uses the Majestic 1,000,000 as a source (grabs the first 500 entries from their list). This page was broken since Amazon discontinued the Alexa service. The Fortune 500 site still uses the same datasource, but the script was crashing due to sites with borked SSL implementations which caused PERL to abort on an exception that I never figured out how to trap or ignore. As such, I’m now manually maintaining an exception list of such sites in the script and testing them is bypassed to prevent the script from crashing. Obviously, this is not ideal, but I found no better solution so far. We now return you to your regularly scheduled NANOG chatter. Owen <http://www.delong.com/ipv6_alexa500.html>
