Hi! 1) RIPE NCC policy requires all routes must be present at the RIPE DB and RIPE IPs could be officially announced outside RIPE Region. 2) Resources owners don't know anything about these routes.. so it means that ranges were announces without permission by third party company.

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

Why can't they be announced from ARIN ASN?  Many network ranges issued by RIPE are held by companies with operations in north america and are announced in North America from North American ASNs.

If you are saying that the announcement from Level 3 is not on behalf of the companies for whom you are the sponsoring LIR, then, perhaps the registered customers (to whom the addresses are listed in whois) should contact Level 3 directly so that they can validate the resource registrants properly before removing the routes.

If I misunderstand what you are attempting to say, I apologize, but, your message is hard to understand.
