From JUllrich at sba-research.org Mon Apr 23 15:19:00 2018 From: JUllrich at sba-research.org (Johanna Ullrich) Date: Mon, 23 Apr 2018 13:19:00 +0000 Subject: High amount of v6 prefixes at CATNIX and SFINX Message-ID: <1524489540656.44918@sba-research.org> 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!
