Hi everyone, I found many ISP announced bogon prefix, for example: OriginAS Announcement Description AS7018 172.116.0.0/24 unallocated AS209 209.193.112.0/20 unallocated my question is why the tier1 and other ISP announce these unallocated bogon prefixes, and another interesting question is: If I am ISP, can I announce the same bogon prefix(172.116.0.0/24) with AS7018 announced? Will this result in prefix hijacking?
