Port scanning - any way to contact the provider?

We're getting thousands of port scannings from
GB/United Kingdom/mobile-032-148-149-213.mycingular.net
where the MAC address is always the same, but the IP address changes (but always mycingular.net)

any suggestions?

Port scanning is not against the law, I would however review your site's security posture and ensure that you have things locked down. If you continue to get scans someone is looking to find a way in. Now is a good time to do security assessment and even do a port scan your self from outside your network and see what the scanners are seeing.

Like belowzerotech posted above, you should also send an email to abuse@att.net. ATT has a very robust security depatment and I sure they can at least look into the source since it is within their network(s).
