establish a large number of connections and make a large number of requests in a very short period of time.Here are some of the DDoS features that we can follow to resist DDoS (including but not limited to):
Attacks often originate from relatively fixed IP or IP segments, with each IP having a greater number of connections and requests than the real user.Note: This does not indicate that the request represents a DDoS attack. In many network architectures that use NAT, many clients use
