destination option for IPV6 */public static final Short ipproto_ipv6_opts = 60;SRC: Source IPDST: Destination IPThe following is the principle of flood attacks based on IP packets:Constructing IP packets with undefined protocol fields for flood attacks constructs an IP packet that represents this field in the upper layer protocol with a protocol type that does not belong to any of the assigned definitions.
We often encounter some problems, such as http cc attacks and FTP TCP-FLOOD attacks, as shown in, we can see the continuous anonymous speculative attacks of illegal users. at this time, we have a variety of solutions. You can try to solve this problem by blocking the IP address. Of course, you need to write a shell to determine how many times a user attempts to log on and block it. CC is an attack

I captured the packet and calculated that a packet contains more than 400 bytes. When I captured the packet, it was about 488 bytes (the specific packet size was not fully confirm

Attack, the attacker will forge a large number of IP address, to send the RST data to the target, so that the server does not serve legitimate users, thereby achieving the victim server denial of service attacks. 3.
