TierraNet (ASN 10732) is advertising 188.8.131.52/19, which includes 184.108.40.206 (ns1.netcolony.com). ARIN reports that they've only been allocated 220.127.116.11/20 and that the other half of the /19 that they're announcing (18.104.22.168/20) is unallocated. Perhaps ARIN has reserved the entire /19 for TierraNet, but only actually allocated the lower /20 to them? Perhaps TierraNet is announcing their /20 as a /19 to get past Sprint's route filters? -Richard
