Have you checked out https://stat.ripe.net/resource/131.143.0.0-131.143.207.255#tab=database yet? it has some nice graphs showing all the historical announcements from that range. Sadly the page takes forever to load due to the size. However, I failed to find the 131.143.0.0/16 range from the ARIN "Cleared for Waiting List" CSV, may I ask how you found that range? btw, i'd recommend signing up for https://www.arin.net/reference/research/whowas/ as that's probably your best bet. let us know how it goes! -- ezri _______________________________________________ NANOG mailing list https://lists.nanog.org/archives/list/[email protected]/message/YKBST57LI3OE7BRKZYYPW77EXJZYJ4H7/
