Why should we announce tiny recycled blocks? If there is a /16 in the

wouldn't we allocate all the free /24's to a single entity and
instruct the entity to announce it as a "holey" /16? The existing /24
holders will override (punch holes in) the /16 for their /24's.
Except when there are /24-holder outages, at which point their traffic
gets hijacked by the /16 announcer. Would you want to trust some random
company to not take advantage of that situation in any way (collection of
passwords, sampling your web traffic, putting up a fake "your org" web
site, etc.)? As a holey /16 announcer, would you want all the junk
traffic that results from /24-holder outages? What if one of them was
running NS's for a popular DNSBL, and their outage basically caused a DDoS
attack against your network?
