ATT Network Security Team

Anyone from the ATT Network Security Team on the list able to help with a
single IP that ATT has blackholed?

Emails to my account reps, noc@att.com, netsec@att.com and tickets go
un-responded too. MIS Helpdesk states they have no way to contact the
Network Security team to get this IP delisted.

Let me know...

Thanks,

Adam
