64.106.198.10 is routed to AS14492 - owner of that AS (see www.arin.net): OrgName: DataPipe OrgID: DATAPI-2 Address: 80 River Street, 5th Floor City: Hoboken StateProv: NJ PostalCode: 07030 Country: US I've tried to trace 64.106.198.16 and than 64.106.198.15, 64.106.198.17, 64.106.198.18 etc. I can't believe that: Only .16 is blocked some AS'es before 14492!
