[44net] Is 44.159.159.0/24 allocated?

Hi there, I found an organization called SSL Corporation (AS38281) start announcing 44.159.159.0/24 since 2021-07-29 14:08:00. I found it here: https://radar.qrator.net/search?query=44.159.159.0%2F24 It is strange with that a renumber plan which says 44.128/10 will be used for radio only was just came out several days ago. I tried to find it on portal, but there is not such a prefix. I also tried to look it up with whois, but it reports a database error: $ whois -h whois.ampr.org 44.159.159.0 # # ARDC WHOIS data and services are subject to the Terms of Use # available at: http://www.ampr.org # # If you see inaccuracies in the results, please report them at # https://portal.ampr.org/contact-us.php # Database error# # ARDC WHOIS data and services are subject to the Terms of Use # available at: http://www.ampr.org # # If you see inaccuracies in the results, please report them at # https://portal.ampr.org/contact-us.php # This prefix is announced with a route object: route: 44.159.159.0/24 origin: AS38281 descr: Assigned by AMPRNET for radio experiment usage. admin-c: Charles Wang tech-c: Charles Wang mnt-by: MAINT-AS38281 changed: charleswang(a)nekollc.com 20210729 #13:20:12Z source: RADB I am here to ask if this announcement authorized? 73, Soha Jin
