I need suggestion related this issue. We are getting DDoS every two days and its small DDoS last for 5 to 10 min. but sometime its longer in that case we call ISP and they
null route specific targeted IP for sometime and we moved service to new IP.
Now question is, is it possible we setup private BGP with our ISP and we do null route from our router so it trigger
blackhole null route on ISP route? In short we need control of doing null routing, calling every time ISP isn't good solution because sometime they are busy then we have to wait in line.
Can anyone suggest what we should do? We are small company and can't effort buying outside service to scrub DDoS they are expensive.
