Start from reading some documentation. https://www.ripe.net/manage-ips-and-asns/db/support/documentation/ripe-database-documentation/types-of-queries/16-12-historical-queries "It is possible to query the history of operational data objects that still exist." It has been already pointed out that this /15 could have been part of something bigger or, quite contrary, part of two separate /16 or even something completely different, which means that the original object could be non-existent. Checking this out is left as an exercise for the reader. Piotr -- Piotr Strzyżewski Silesian University of Technology, Computer Centre Gliwice, Poland
