IPinfo Geolocation Advice Needed
by Mark Blackford 24 Oct '25

24 Oct '25

Greetings, Does anyone have any suggestions on how to get IPinfo to properly report Geolocation for NNI pint to point type circuits? I have a geofeed that they are ignoring, but I have two prevailing theories. One - someone put our entire ARIN aggregate in it last month and now it overlaps everything in the feed. I read that overlapping prefixes cause confusion. I took it out of the feed today, but IPinfo is so secretive I have no idea if they will remove it. Two, and the more likely theory based on their boast on how they beat the competitor by thousands of miles, is they are reporting on the wrong end based on their ping scans. They ping the hub end of a /31 and disregard the other end that is usually two to three states away. Therefore , they are the ones horrible off an their competitors are spot on. Should I not be reporting the point to point /31 and only use he customer /32 end? Any other advice in properly identifying the location for Ipinfo would be awesome. All the other providers seem to properly follow my geofeed, and I have no issues with them. Thank you very much, Mark Blackford

mitigations for the BGP vortex attack
by Martin Tonusoo 24 Oct '25

24 Oct '25

Hi. I recently read an interesting research paper that I don’t think has been shared here yet: https://www.usenix.org/system/files/usenixsecurity25-stoeger.pdf I would throw out two additional thoughts related to "Partial Mitigations"(6.1): 1. Usage of modern, multi-threaded routing daemons which are able to take advantage of multi-core control plane CPUs. 2. Control plane CPU usage monitoring. BGP per-neighbor sent and received UPDATE messages rate monitoring. For example, Junos supports this via SNMP, telemetry or RPC. In the "Safe BGP Communities"(6.2) paragraph the paper advises networks to cease the support of "Lower Local Pref Below Peer" community. As the BGP vortex forms only when both the "Lower Local Pref Below Peer" and "Selective NOPEER" communities are present, then perhaps alternative approach would be to cease the support of those two communities together. In other words, both communities would still be allowed separately, but not together. I did a brief analysis on RIPE RIS data for NTT, GTT and Sparkle "Lower Local Pref Below Peer" and "Selective NOPEER" type communities and the combination where both types are attached to the prefix are rare. Finally, I wonder if or how much the attack is amplified if the adversary ensures(for example, using communities) that each announced prefix has unique path attributes and thus there is an UPDATE message per prefix.

Back in 80s I read a book ...

A surprisingly good interaction (Summit)
by Warren Kumari 20 Oct '25

20 Oct '25

Hi all, This really isn't the sort of mail that I normally send, but I had such a good interaction with an organization that I wanted to share. I have had a server hosted at Summit (summithq.com, formerly ServerCentral / Deft) for ages. After many years of faithful service, it finally threw a drive, and so I shipped them a new one to replace it… All of my interactions with Summit were great - everyone I dealt with was super responsive, competent, helpful, and friendly. It took me a few weeks to get the new machine ready to be shipped, and someone checked in with me a couple of times during this to make sure that everything was OK. The machine finally arrived at their loading dock at ~10:30AM, and was installed (with coordination) before noon. They offered to recycle my old box, and were seriously a pleasure to work with the whole time… This is an odd email to be coming from me — I'm much more inclined to kvetch and snark — but I am really impressed with Summit and their support. W P.S: I have no relationship with Summit, other than being a happy customer.

IP Address support in spreadsheets?
by Bryan Fields 20 Oct '25

20 Oct '25

Has anyone found a solution to represent IPv4 addresses in a spreadsheet, preferably Google Sheets? I'm not here to debate the use of spreadsheets for tracking IP addresses, just find something better than storing v4 dotted decimal as text in a spreadsheet. We don't need v6 at this time; we're using a spreadsheet for tracking addressing, v6 is beyond us. At minimum we need to store it as a 32 bit INT, and display as dotted decimal. If there's some way to make it aware of subnet slash notation, so much the better. I'm a bit at a loss as to why there's no IPv4 number format with how often spreadsheets are the source of truth in some rather large service providers. Again, not looking for non-spreadsheet solutions to this, and ideally a web interface spreadsheet would be best for sharing. We don't need a real database if it's on the web :-) -- Bryan Fields 727-409-1194 - Voice http://bryanfields.net

We accept laptops, desktops, monitors, tablets, servers, and related accessories from companies and individuals. *We provide full-service ITAD with secure onsite pickup, certified data erasure/destruction, refurbishment and remarketing, end-of-life recycling, and custom ESG reporting; all anchored in rigorous security and compliance.* Our process provides a verified chain of custody, monitored locked transport, restricted facilities with video surveillance, certified destruction with certificates, routine internal/third-party audits, and background-checked, confidentiality-bound staff. By donating, your organization not only diverts e-waste from landfills but also creates lasting impact for families without reliable access to technology. *Learn more *about our donating devices at http://www.compudopt.org/devices NANOG affiliated organizations interested in donating devices, please click HERE (https://airtable.com/appElXNQvUaLJztUn/shrUyu3sTxiPPEZTV) and a member of our team will follow up with you to coordinate logistics. *START HERE *(https://airtable.com/appElXNQvUaLJztUn/shrUyu3sTxiPPEZTV) *** Stay Connected* ------------------------------------------------------------ http://www.facebook.com http://www.instagram.com/nanog_org/ http://www.linkedin.com/company/nanog/ https://www.twitter.com/nanog/ http://nanog.org
