Illegal access to the Yantai. Net Club website in recent days

The Yantai. Net Club website encountered an exception report in the last few days. So I investigated the site's IIS log and analyzed it. I found that more than 100 illegal IP addresses were accessed as follows:

Number of attempts	IP address	Region
4904	211.64.120.192	Shandong Jiao Tong University, Jinan City, Shandong Province
223	74.6.74.159	USA
190	222.80.77.209	Kashgar Telecom, Xinjiang
181	202.108.211.101	Beijing Netcom
160	222.183.217.187	Chongqing Jiangbei Telecom ADSL
148	124.156.191.67	China
112	222.88.189.247	Henan hebi City Telecom ADSL
100	220.169.248.6	Hengyang City, Hunan Province

Take the first visit to 211.64.120.192 as an example. The path of the Club website to be accessed is as follows:

As a result, his IP address is blocked. Although this does not work, he hated the hacker behavior. However, they hate crazy search engine crawlers, Baidu crawlers, and sogou crawlers. In addition, many websites have a headache for this problem. I hope you can work together to come up with a good solution to this problem. I will try to analyze and solve this problem in the near future.
