Ranges announced by Level3 without permitions.

[Alfa Telecom <ripe () alfatelecom cz>]

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.
