I can routes are wrong for all /24 annoucements. May be contacting Level3+Telia+AboveNet+Hurricane Electric since all these are upstream providers of AS29791 which is your upstream carrier? I guess they would be able to neutralize effect significantly by filtering those routes? On Wed, Feb 1, 2012 at 12:27 AM, Tony McCrory <tony.mccrory@gmail.com>wrote:
Surely something is better than nothing. Advertise the /24's and the /25's, see what happens.
At the least it's a step forwards until you get their routes filtered.

Upstream requirements. Additionally, I don't believe it would do us any good. If they're announcing /24 now, why would they not announce a /25. On Jan 31, 2012 1:19 PM, "Grant Ridder" <shortdudey123@gmail.com> wrote:
Hi,
What is keeping you from advertising a more specific route (i.e /25's)?

Greetings all.
We've been in a 12+ hour ordeal requesting that AS19181 (Cavecreek Internet Exchange) immediately filter out network blocks that are being advertised by ASAS33611 (SBJ Media, LLC) who provided to them a forged LOA.
The routes for networks: 208.110.48.0/20, 63.246.112.0/20, and 68.66.112.0/20 are registered in various IRRs all as having an origin AS 11325 (ours), and are directly allocated to us.
The malicious hijacking is being announced as /24s therefore making route selection pick them.
Our customers and services have been impaired. Does anyone have any contacts for anyone at Cavecreek that would actually take a look at ARINs WHOIS, and IRRs so the networks can be restored and our services back in operation?
Additionally, does anyone have any suggestion for mitigating in the interim? Since we can't announce as /25s and IRRs are apparently a pipe dream.
