DNS Settings

Dynamic domain name resolution requires a special DNS server. This server maps domain names to IP addresses and processes the resolution requests of clients.

Context

After receiving a resolution request, the DNS server checks whether the domain name belongs to its authorized sub-domain. If yes, the server translates the domain name into an IP address according to the database, and then sends the result to the client. If the server cannot resolve the domain name, it sends the resolution request to the upper-level DNS server. This process continues until the DNS server finds the corresponding IP address or detecting that the corresponding IP address does not exist. The DNS server then returns the result to the DNS client.
