Currently we see 414 LIRs that have more than one /22 from the range 185/8 registered to them.

That's quite interesting.

I had a look in the DFZ (as received from Level(3) this afternoon)

I can see 13742 advertisements of space from 185/8, 5 of them are for /21 and 1 is for a /20.  The advertisements include de-aggregations (e.g. a /22 and a /23 for the same prefix)

Looking a the /22 adverts. there are 5613 in the DFZ with 4090 distinct AS origins.  This means that over 1500 AS's are advertising more than one /22.
