Recently, I found that visiting all Baidu-related websites was surprisingly slow, but other websites were okay. I always thought it was a problem with Baidu. So in desperation I can only use other search engines, such as secret search .
Find a reason:
- I use telecom broadband, but the parsed Baidu's IP is the IP of Baidu's Unicom server, so it is extremely slow.
1.1 https://www.ip138.com/ You can view your IP and broadband provider.
1.2 ping www.baidu.com. Check the resolved IP and compare it with the network segment provided on the following page to see which operator the IP belongs to.
IP address segments of China's operators (Telecom, China Unicom, China Mobile, China Railcom) - Manually check Baidu's server IP in Telecom on the Internet, and then manually modify the hosts file, the problem is really solved.
- So why is the IP resolved by the domain name wrong?
It turns out that the domain name server TM didn't know when the setting was wrong, so I should select automatic acquisition, but it was set to a fixed value.
After changing to automatic acquisition, it is OK. - But the strange thing is that basically only Baidu is affected, but other websites can basically be used normally. Observe the result of ping,
www.baidu.comandblog.csdn.netwait, there is no difference between the two settings. Only ping makes awww.baidu.comhuge difference. Hope that the great god who knows the reason can share the reason further.
