The most basic defense at the network layer is RFC? 2827 [3]. Using input source filtering, ISP refuses to route a packet whose source IP address does not belong to its source subnet further. Input source filtering can effectively prevent SYN flooding attacks disguised as IP. However, this method is useless at present because it is difficult to deploy on a large scale. Moreover, input source filtering cannot resist distributed attacks.

我是不是要问一句，你连这一点都不知道，还配写武侠小说？这就是陈启的回应。
尚书抬头看了看皇上，咬牙接着说道。
I remember the fighting was fierce, Almost everyone's barrel was red, But that's it, There is still a "slip through the net" in these things, Towards the end of the third exchange of fire, And one came up from the right side of the position, I turned around and shot it, After pulling the trigger, One shot hit him in one of his hind legs, I watched helplessly as the impact of the bullet knocked its hind legs off its body. But it doesn't seem to care, It is still a leap forward, He threw himself on a soldier named Zhou Xiaolin beside me. Biting his thigh and not letting go, Ge Xiaolin's painful "wah-wah" yelling, I think we've just had an attack, A little respite, He asked two people to help him get this thing off his leg with me. As a result, I was busy for nearly 5 minutes, Break this thing up with a dagger, But it did not let go, Finally, I used a faster knife. It's only by opening its mouth from the outside to the inside that it's allowed to let go. But Zhou Xiaolin is still relatively unfortunate, Although the thing was loose, almost a small watermelon area of meat was torn off on his bitten left thigh, and the thigh bone inside could be seen from the front. A cyan artery on the outside of the thigh was also exposed for a while, while he himself was in a coma due to excessive blood loss and severe pain.
The attack uses the method of sending a large number of domain name resolution requests to the attacked server, Usually the domain name requested to be resolved is randomly generated or does not exist on the network. When the attacked DNS server receives the domain name resolution request, it will first look for whether there is a corresponding cache on the server. If it cannot be found and the domain name cannot be directly resolved by the server, the DNS server will recursively query the domain name information from its upper DNS server. The process of domain name resolution brings a great load to the server. If the number of domain name resolution requests exceeds a certain number per second, the DNS server will time out to resolve domain names.
