Sending up to a /24 is an oversimplification in today's post-IPv4
exhaustion world. ARIN now has a "Dedicated IPv4 block to facilitate IPv6
Deployment" (23.128.0.0/10) from which they are may allocate in /24 thru
/28 sized blocks.

RIPE has tested visibility of longer than /24's and reported on that in
2014 and 2015, both with and without IRR entries.
