Interesting; I see similar results for my address space. Two
addresses, one of which hasn't been attached to a machine for a decade
and the other a virtual IP on a web server where the particular IP
never emits connections. Magnitude's only "0.48" for both but still,
they shouldn't even appear.
I suspect a bug in their system. I checked a handful of unrouted blocks
from our address space and eventually hit a /24 from which senderbase
lists an IP with magnitude 0.48, but the space hasn't been routed for 13
months. They say they saw something from it on 2010-04-06...which I'd say
is highly unlikely.
