I don't think you are at all wrong; at this time Atrivo (AS) are still
announcing blocks in three Class B's that are assigned to other people:
138.121.0.0/16 listed as Ready Systems
146.100.0.0/16 listed as Zust-Ambrosetti (in Italy)
170.208.0.0/16 listed as Los Angeles County ISD
Here are the full current routing tables for those blocks ...
138.121.16.0/21 10912 Internap
138.121.52.0/24 16631 Cogent
138.121.53.0/24 16631 Cogent
138.121.56.0/22 16631 Cogent ***
138.121.128.0/19 26346 27595 Atrivo
138.121.224.0/20 6939 Hurricane Electric
170.208.0.0/24 16631 Cogent
170.208.0.0/20 4474 27595 Atrivo
170.208.6.0/24 16631 Cogent
170.208.7.0/24 16631 Cogent
170.208.8.0/24 16631 Cogent
146.100.32.0/19 4474 NLayer
146.100.48.0/20 4474 27595 Atrivo
146.100.64.0/19 4474 NLayer
I have successfully pinged one IP in each of the blocks in that list,
so I am fully satisfied that all the blocks are live and being routed.
I personally telephoned Cogent's NOC two days ago to ensure they were
aware of the situation; I also attempted to reach Michael J. Hammons
(Sr. Director of Operations at Cogent) when no action was taken, but
was unable to reach him and my call was not subsequently returned.
I hope to have some helpful news of a short term remedy fairly soon.
