I have previously contacted Swisscom about it back in 9/2003 and received the following response:
we are filtering on RIR minimal allocation boundaries. This creates some routing holes which we fill by these semi-default routes (towards our upstreams) for our customers' perusal.
luckily, things like this are never leaked into the open internet by multi-homed customers and weak filtering policies. </sarcasm> randy
