IIRC, at some time, perhaps when CIDR was deployed widely and having something other than IPv4 was a hot topic, there was a discussion on releasing 240/4 in IETF.

There have been many discussions about 240/4 in the IETF. For some examples, query “240/4” in the ‘ietf’ mail archive <https://mailarchive.ietf.org/arch/browse/ietf/?q=%22240/4%22> on mailarchive.ietf.org. —gregbo
