I would hope that the APNIC would opt not to assign networks that would 
contain 1.1.1.1 or 1.2.3.4 to customers for exactly that reason.  The 
signal-to-noise ratio for those addresses is likely pretty high.  The 
noise is likely contained on many internal networks for now because a 
corresponding route doesn't show up in the global routing table at the 
moment.  Once that changes....

I could see holding those prefixes aside for research purposes (spam 
traps, honey pots, etc...).
