This experiment is a comprehensive test of HTTP fundamentals and DNS servers.
1, Upload the test file, which is the sogou search homepage downloaded from the internet.
2, First use the IP address range to determine if the HTTP service is functioning normally.
3, Modify the baidu zone file baidu.zone by changing the IP address.
4, Remember to restart the DNS server.
5, Confirm whether the DNS resolution results are correct.
6, Due to caching issues, the expected occurrence rate of the experiment is low; not using well-known domain names will increase the success rate.
