--- Comment #4 from Rodney W. Grimes <rgrimes at FreeBSD.org> ---
This is probably the same as in
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=226688.

I understand a desire to have the 255.255.255.255, but this is really a
degenerate form in both bug reports of 240.0.0.0/4 as that already covers this
range in its use, the 255.255.255.255 is not needed in the table in any way, it
servers no additional purpose.

The example here though does not include 240/4 for some reason, which it
probably should be in the table if they are attempting to block reserved or
unlikely to be in use IP addresses.

I agree there is a bug, but I also assert that it is a very low priority to
spend a great deal of effort to fix.  If there is a simple fix in the radix
code or an interface error has been made, then great, lets get it fixed.
