ISP can block volumetric DDoS attacks (layer 2/3).

When the attack is build with tools like LOIC, SLOW LORIS, HULK, Hping,... the ISP cannot do anything.

The ISP only count packets and look on traffic anomaly. All the tools used today for DDoS are working on layer 7 and 
have similar behaviour as a legitimate connection.

The right strategy is ISP service for volumetric attacks and on premise DDoS Defense solution for Layer 7 attacks, 
reflective attacks (spoofing), specially crafted packets attacks and other kind of attacks which may be generated by 
internal hosts compromised.
