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?
Thanks!
