ARIN, RIPE, APNIC, AFRINIC, LACNIC. If you have announced addresses from one in the others region and have not received warnings it's just a matter of time. ARIN is the most vigilant. There was a time they used to do ping sweeps and nag people about not utilizing their addresses which led to my putting a 1U server on a /17, /19 and some smaller networks with Labrea responding to pings for all of it. They stopped doing that which led to people hoarding IPv4 space and now putting a monetary value on it which is dumb dumb dumb.
replySurely that not the case. Check any public BGP looking glass: Arelion/Telia uses RIPE space in the USA, Lumen/Level uses APNIC space in Europe and so on.
replyARIN are the most aggressive about it. Maybe others just don't care any more. They certainly used to. I would never hear the end of it. Perhaps others pushed back enough to stop that practice elsewhere.
