The code in most hosts will not allow the entry of an IPv4 address within 240.0.0.0/4 as a unicast interface address. FWIW, it’s also a fact that at least one address in 240.0.0.0/4 is not acceptable for use as a unicast address since it’s the universal broadcast address (255.255.255.255). >> The ARIN region is very behind compared to RIPE or LACNIC. >> https://rpki-monitor.antd.nist.gov/ >> There have been extensive discussions recently about why.

At HE, we found a huge uptick in IPv6 sage certifications when we handed out T-shirts. Perhaps a “My resources are signed… Are yours?” kind of T-shirt might help.
