from some RIS servers like server 15. The problem was those prefixes orginated from our AS and in soem cases from our customers AS that don't have IPv6 peer at all. Yesterday I noticed it is not a IPv6 bogon. It's the hex version of our IPv4 prefix. Check this example out:
4f7f::/19 Time: 2017-06-21 00:16:17
79.127.0.0/19 Time: 2017-06-21 00:16:17
have you noticed this problem?
Hello Shahin, I don't see that IPv6 prefix in the raw update files for 2017-06-21 or 2017-06-20 for RRC15. If you can give me an exact filename and timestamp where you see this, I could take a closer look. Also what are you using to parse the files? bgpdump?
