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!
