I feel so ... dumb ;-)  127.0.0.2 will have similar problems.  The thing 
to choose would preferably be something that's not resolveable, and is 
unlikely to ever be used in a real link.  SURBL has something like 
"this-is-not-likely-to-ever-appear.<queryroot>".  Perhaps the BCP should 
  simply give suggestions on how to invent a test string rather than 
mandating a specific one.  Or punt.
