Yup sending an email to support (RIPE) for clarification.
I would be happy if you could share a summarized edit of the response you get back.
But Twitter NOC is adamant that they are not doing the wrong thing (advertising unallocated address space) because it shows in RADB-GRS via RIPE Whois
The routing policy (NOT assignment!) shows up in RIPE Whois. Because RIPE mirrors objects in RADB. Where Twitter themself have registeret only route policy objects for both 188.64.224.0/21 and smaller /23 and /24 prefixes inside the main /21 prefix. ~ > whois -h whois.radb.net 188.64.224.0/21 route: 188.64.224.0/21 descr: Twitter Route origin: AS13414 admin-c: NETWO3685-ARIN tech-c: NETWO3685-ARIN notify: noc@twitter.com mnt-by: MAINT-AS13414 changed: frehoie@twitter.com 20160112 #15:43:10Z source: RADB http://www.radb.net/ "Merit RADb is a public registry of network routing information that assists with the transfer of data over the Internet. For over 20 years, Merit RADb has been serving the Internet community. Thousands of organizations that operate networks have registered their routing policies in Merit RADb to facilitate the operation of the Internet, including Internet service providers, universities, and businesses. The information in Merit RADb enables organizations to troubleshoot routing problems, automatically configure backbone routers, generate access lists, and perform network planning. Any organization with an autonomous system number (ASN) may register in Merit RADb for an annual fee of $495 (U.S. Dollars). Non-profit organizations may register annually for $395." And seeing as RADB is a commercial entity advertising themself with the line "organizations that operate networks have registered their routing policies in Merit RADb". I read it as RADB is only a DB for advertising routing policies. NOT for holding INETNUM assignments. Which concludes I am in agreement with you. I am not sure Twitter is doing the right thing of advertising unallocated space.
