Dear Gurus, Radar tool by Qrator [Reference: https://radar.qrator.net ] claims that Zenlayer Inc. [AS4229] is “umbrella-ing” me by announcing ‘2400::/12’ on top of my more-specific address block. The tool classifies it as a type of hijacking. [Disclaimer: apologies to Zenlayer if you didn’t do it; but that’s the information I received] My neighboring organization also has a more-specific block that falls under The Umbrella too. However, other tools (https://stat.ripe.net , https://irrexplorer.nlnog.net , https://bgp.he.net , etc.) seem unable to see that particular announcement. Questions: 1. Is Qrator claim true? (because I have already tried but cannot verify) 2. If so, should I be concerned? Even though I already ROA-ed *and* IRR-ed my own block, but if “the other end” doesn’t validate, it won’t do any good, correct? (Oh, yeah, the other end also has to somehow “not see” my longer-prefix. But that can happen as well, no?) 3. In that case, what more do I must do? I would extremely appreciate someone helping me out on this matter. Best Regards, Pirawat.
