Flow Tools AS-Path
by Mike Hammett 04 Apr '23

04 Apr '23

One of the reasons to analyze flow data is to make purchase\peering decisions. The sFlow standard seems to only include source and destination AS, though I know some route platforms have extensions to provide additional data. 1) How common is it to have the additional extensions to include that data for analysis? 2) I have seen flow tools that show the entire AS path. Are they just cherry picking which platforms they showcase for the best marketing, or are they enriching the data they receive from "lesser" platforms from an outside source? For that purpose, knowing what ASes your data goes to is useful. It's even more useful to find an upstream network that includes a bunch of those. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com

Caveat emptor: avoid Inseego 5G products unless you still believe in classful routing
by Matthew Petach 28 Mar '23

28 Mar '23

In the category of "I can't believe I still have to worry about this in 2023" comes an unfortunate discovery I made recently when setting up a network for a local non-profit. The Inseego FX2000 5G router looked like a nice product, it supports OpenVPN out of the box, flexible firewall rules, etc. What I did *NOT* expect from a device made in 2023, and didn't think to ask about ahead of time, is whether it supported classless routing. Setting the unit up, I discovered the hard way that the developers are apparently still working from 1989 textbooks. The only netmask the router will accept for a 10.x.x.x. subnet is 255.0.0.0. Absolutely refuses to accept a different length netmask. Even the user manual reflects the inherent classful assumption: " IPv4 IP Address: The IP address for your FX2000, as seen from the local network. Normally, you can use the default value. Subnet Mask: The subnet mask network setting for the FX2000. The default value 255.255.255.0 is standard for small (class "C") networks. If you change the LAN IP Address, make sure to use the correct Subnet mask for the IP address range of the LAN IP address " So, before anyone else makes the same mistake I did, I thought I'd give the community a heads-up to avoid the Inseego line of 5G products, as they're woefully behind the times in their understanding of IPv4 subnetting as it exists in 2023. ^_^; Thanks! Matt

Issues with prefix / help needed
by ic 28 Mar '23

28 Mar '23

Hi there, I’m contacting you because after spending 2 days troubleshooting I can’t seem to find a solution to the following. We (AS45021) bought/transffered the 86.104.228.0/24 prefix a few months back because we couldn’t wait longer on the RIPE waiting list. Before you ask, yes, AS45021 is currently single homed, this will change in a week (it requires travelling a few hundred miles and I couldn’t do it before). Since we started announcing this prefix, things have been spotty, at best. While it seems visible in all the looking glasses I tried, it spends sometimes hours, sometimes days, being unreachable (you can try for ex. 86.104.228.1 or 86.104.228.26). I have full access (up to packet capture) on the AS and its upstream. When I ping one of the IPs from various ISPs, I see the ICMP Echo Request and Reply on the wire, going where it’s supposed to go, but it doesn’t reach the pinging host. Pinging any IP of the upstream (AS42275 / 85.208.69.0/24 in this location) works. ROAs and RPKI seem fine to me. I’m starting to suspect that maybe the previous user of the prefix is still announcing it somewhere and “shouting louder” than me. It seems when I clear sessions, it immediately works for a while, then stops. Do you all have any idea what I should check / try next? BR, Michel

ARIN 8.3
by Nicholas Warren 24 Mar '23

24 Mar '23

https://www.arin.net/participate/policy/nrpm/#eight3 What are people's experience with receiving several transfers in a years' time? In 8.3, it states there is a waiting period for transfer sources. There is nothing about a waiting period for receivers. What's the likelihood of there being a waiting period for receivers? If there is a waiting period for receivers, would section 8.5.7 override that period? Thanks, Nich Warren
