Re: Suspecious anycast prefixes

Hi NANOG, I manually extracted the origins and their org info for the announced block of prefixes. All these prefixes were observed being originated by at most four ASNs simultaneously. I suspect they provide anycast or IXP service, but not positive. Please confirm my conjecture if you know them.
