Hello,
I have in As-stats an as23456. I don't know who this AS is? After research this would be my version of netflow which would be 5, but I am in Netflow 9? Anyone know this problem?
Thank you

Hello,
This is the AS used to "translate" all the 4-bytes ASNs into a single
2-byte ASN, for the router's software not fully compatible with 4byte
ASNs. We used to see it within BGP paths, but this is becoming
unfrequent in 2021. What kind of gear do you run ?
Kind regards,
Clément Cavadore

Hello Matthieu,
In order not to disturb the rest of the list, I think we'd better
continue in english, even if I'm french :-)
Maybe you should think about upgrading your ASR to a newer IOS version,
as yours may not fully support 4bytes ASN. I bet you don't have any of
those in your stats, and then, that AS23456's stats is equivalent to an
aggregate of all the traffic you have with the 4byte ASNs.

Ok Clément,
I understand, and it makes me work on my english ;-)
The version IOS is 16.6.2 (Everest) on the ASR. In the release doc, this date from 2019 (https://www.cisco.com/c/en/us/td/docs/routers/asr1000/release/notes/xe-16-6/asr1000-rel-notes-xe-16-6.html).

I himself respond. The real date of IOS 16.6 is July 2017 not 2019.
