Ranges announced by Level3 without permitions.

Hello All! Maybe somebody could help me with some issue: Ranges below are announced by Level3 79.110.224.0/20 *[BGP/170] 08:23:34, MED 0, localpref 150, from 213.248.64.245 AS path: 3356 79.110.64.0/20 *[BGP/170] 08:25:07, MED 0, localpref 150, from 213.248.64.245 AS path: 3356 Both ranges are from RIPE region and couldn't be announced from ARIN ASN at all. We're sponsored LIR for both companies, I sent several emails to Level3 noc, made several calls but they still announce these ranges. ------------------ Andrew
