There was an excellent report published in 2008 by HostExploit that showed the connections between Atrivo and those for whom it provided downstream services. One of those such customers was a Chinese provider called HostFresh. I thought it might be interesting to look at two IP blocks which were previously part of the Atrivo network - 188.8.131.52/21 and 184.108.40.206/21 - but are now routed by others.
Below we can see the information registered about HostFresh:
aut-num: AS23898 as-name: HOSTFRESH-AS-AP descr: HostFresh Internet descr: Internet Service Provider country: HK notify: email@example.com
