21.DNS Resolver Commands
DNS (Domain Name System) is function to manage server domain names.
Domain names are named based on hierarchical structure rules. The DNS
server, which corresponds to domain name hierarchies, manages a
mapping between domain names and IP addresses. Access to a web server
becomes available after sending an inquiry to the DNS server and obtaining
an IP address from the domain name (name resolution).
A resolver is a client that sends a name resolution request to the DNS
server.
In this chapter, you will configure a DNS server used when this Switching
Hub requires name resolution.

You can also configure the response waiting time (1 to 60 seconds) from the DNS server,
register a static DNS table, and check and delete DNS cache.
