During development, if we cannot open a website, the first thing we think of is to ping the domain name of this website to see if it is a server problem.
Or in another case, the website is deployed on multiple servers at the same time, and there is a problem with one of the lines, but we are not sure which line is, we will choose to test the problematic line computer, ping the domain name , You can know which line and which server it is.
There are many other situations where the ping operation will be used. At this time, there will be an illusion that the server cannot be pinged, but the server can be accessed remotely. The above phenomenon is what I want to talk about today
. Ping operation is enabled and disabled on the server.
