bogon identified? how to track down bogus IPs/ASN's

My turn for the newb question:

I've got a traceroute with this IP in it thats close to the end of the trace.    

Chasing down this IP to see who the ISP a friend is using, figured out
the diff between ARIN and APNIC whois for IPs (..bit of a learning curve, not
sure why there's not just one whois interface syntax).

 whois -h -m 

shows only the upper /22 being registered with APNIC (if you do -m on
.16.0/22, there's no entry).

So it seems to me these Ips arent registered properly with APNIC (could it
be cross-registered with another RIR? Well it's not with ARIN who'd be the local.)

But I do see this block in global bgp tables so it wasnt like someone decided to use
10.10.10/24 or 1.2.3/24 in their routing infrastructure. They're actually announcing;

 sh ip bg  ends in a path with  394786 135022

looking up 394786 I see avetria networks. looking up 135022 I see nothing at ARIN.

At APNIC I get

as-block:       AS134557 - AS135580
descr:          APNIC ASN block
remarks:        These AS numbers are further assigned by APNIC
remarks:        to APNIC members and end-users in the APNIC region

but nothing more specific.

However, this does show up in radb as avetria networks as well. (and various geolocate
DBs put it in though i know it's in use in Kitchener ontario).

So what's not matching up here?
