Configuration Guide Configuring DNS
The procedure of dynamic domain name resolution is as follows:
14. A user application program (such as Ping or Telnet) requests the IP address mapped to a domain name from the DNS
resolver of the system.
15. The DNS resolver queries the dynamic cache at first. If the domain name on the dynamic cache does not expire, the
DNS resolver returns the domain name to the application program.
16. If all domain names expire, the DNS resolver initiates a request for domain name-IP address conversion to the external
DNS server.
17. After receiving a response from the DNS server, the DNS resolver caches and transfers the response to the application
program.
