I have not seen any changes yet, although I did get an automated response from their abuse address that they received my message. Also, to answer another question I have not changed backbones in over two years. I largely suspect that this is an issue of a simple typo and not anything malicious. -- ----------------- Brian Raaen Network Engineer email: /braaen@zcorum.com/ <mailto:braaen@zcorum.com> Gustavo Rodrigues Ramos wrote:

Hi Brian, has someone from at&t contacted you or have you noticed any change?

Thanks, Gustavo.

I have sent a complaint to the AT&T abuse contact from my ARIN contact address asking them to stop announcing the route.

I appreciate the offline replies. After doing some more research myself the issue appears to be related to the fact that AT&T is announcing the block directly. I did show "ip bgp 72.14.76.0" in a couple routers and some showed the route originating in 701 (they were able to reach it) and others showed it originating in 7018 (and they could not reach it).

Here is my question, since I am an ARIN admin contact for the IP block how is the best way to get AT&T to quit announcing the block.
