Hello!
Relying on RIS data, I am currently investigating BGP announcement for IPv6 for my research.
For some reason, CATNIX and SFINX members appear to announce a lot more prefixes than the others.
While I found typically less than 50 /32 prefixes for the other Internet exchanges, I see almost 900 /32 for SFINX and even 9000 /32 for CATNIX.
I wonder whether there is a specific reason, e.g., with respect to aggregation or policies.
I am really looking forward to your reply.
Thank you a lot for help!
Regards,
Johanna
