That applies to *any* field when you do a "!=" comparison; it's not 
unique to ip.addr (that's probably the most common example, but tcp.port 
and udp.port are probably also somewhat common places where this 
surprises users).  If we're to pop up a warning, I'd pop it up for any 
use of "!=", and offer a "don't show this dialog any more" checkbox so 
that the user can say "OK, I understand now" and not be bothered in the 
future.
