DNS concept: people are used to memorizing domain names, but machines only recognize IP addresses. domain names and IP addresses correspond one by one. The conversion between them is called domain name resolution, domain name resolution must be completed by a dedicated domain name resolution server, which is the DNS server.

Follow the next step to complete the following operations.
