nDepth query for IP

I open up the nDepth query and enter my IP say 10.20.30.40 search.  The nDepth query seems to see that as, I need to find "10" or "20" or "30" or "40" when I actually want it to search for "10.20.30.40".

What am I doing wrong?  I'm wanting to find any traffic with a certain IP in any field.
