Interpretation:

137.194.0.0/16 is assigned to ENST and has been announced by AS1712 since 2001.  See also:

Other announcements from AS1712 have appeared on 20091018 
imost ceased on 20091026, about a month ago.
74.118.148.0/22 is still there and needs to be addressed.

I am sure the RIRs concerned will learn from this and this thread already
contains good suggestions about what/how to learn.

PS: And yes we are going to make the REX tool for querying ASes available soon.
