I'm not sure if this is helpful to this discussion or not, but I recently became aware of a bug in a virtual router using DPDK+VPP which sounds like it could possibly produce a similar issue to what is being described, without the TCP window being a factor. The system used the same process to

You can send over your self-published Geofeed URL (or just direct geo data) to IPInfo at https://ipinfo.io/contact - they’re very quick to respond and take action; I assume the process is similar for IPData. Best Phin On Wed, Apr 21, 2021 at 10:34 PM Brian wrote: > Good day all. I am trying to

Good day all. I am trying to find contacts at ipdata.co and ipinfo.io. I recently acquired new ip space and most places have updated. But the above 2 have not and still show CA as the location for this ip space. Please feel free to email me off the list. Thank you Brian

I'd like to get some data on what actually happened in the real cases and analyze it. If it's a Cisco router at fault, then we have a bug to fix. Even if it's not a Cisco, there may be ways we can help to avoid the situation. However, before we start on solutions, I'd like to get a good

I wanted to get the communities' opinion on this. I am an admin for a quasi-ISP providing cloud hosted desktop solutions for end users. We have POPs all around the world, own our own ASN, and advertise /24s or /23s at each of our POPs fro our large aggregate. As an ISP we submit our blocks to

Nice article explaining a specific BGP corner case not removing routes when TCP window reaches 0. https://blog.benjojo.co.uk/post/bgp-stuck-routes-tcp-zero-window The proposed solution is a new RFC for BGP with the suggestion to introduce a new timer. Fascinating! Jean St-Laurent /CISSP
