I don't want to over-state it, but 'number of prefices' slways feels to me like a potential mis-measure. Not that you don't want to know it, but % of announced space for a given origin-as feels like it might be closer to the story, because there can be so many different ways to announce it as dis- and super aggregates. -G On Tue, Jul 17, 2018 at 1:55 PM, Job Snijders <job@ntt.net> wrote:

Markus Weber from KPN is generating a daily report here and drew similar conclusions: https://as286.net/data/ana-invalids.txt Markus scrapes all routes from the AS 286 PEs and marks the routes for which no valid or unknown alternative exists as "altpfx=NONE".
Thanks. Protein.
So the numbers are not that far off from when I last checked this back in 2016, i.e., less than 1% of the total IPv4 routing table.
Do you have numbers for IPv6, out of interest?
There are ~ 330 IPv6 invalids in the DFZ, and for 70 of those no alternative covering prefix exists.
Kind regards,
