One of our customers has 129.129.0.0/16, and we sure receive a lot of
leaked packets with source and destination addresses in that range
from our upstream. (One of these days I'll try to get those traced :-)

147.28.0.0 doesn't seem like a likely "random" prefix though.  Maybe
an ex-customer/employee of yours didn't clean up their configuration
when they left?
