I recall that, about six years back, I put in a block rule for an entire /15
in the 5.0.0.0/8 range. That was for EOP/Office 365, though. In the
subsequent months a total of two false-positive reports flooded in. I don't
recall it being in the area you mention. Plus you would have noticed it
earlier, I would expect, if that rule is still in effect..
