20.Domain Name System (DNS) Relay
Commands
DNS (Domain Name System) is a 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).
The DNS relay is a function that allows this Switching Hub to receive a
name resolution request from the client and transfer it to the original
DNS server.
TCP/IP network requires a DNS server specified for each client. The DNS
relay function allows you to configure this Switching Hub as a DNS
server.

In addition, you can improve the name resolution efficiency using DNS cache and
configure a static DNS table.
