DNS:
It is Domain Name System used to serve the translation between IP
address and name address.
The switch supports DNS client function to re-route the mnemonic
name address to DNS server to get its associated IP address for acces-
sing Internet. User can specify a DNS IP address for the switch. With
this, the switch can translate a mnemonic name address into an IP
address.
There are two ways to specify the IP address of DNS. One is fixed
mode, which manually specifies its IP address, the other is dynamic
mode, which is assigned by DHCP server while DHCP is enabled. DNS
can help you easily remember the mnemonic address name with the
meaningful words in it. Default is no assignment of DNS address.
