To add a DNS server:

Use the Host Mapping page to view and configure associations between 
hostnames and IP addresses. You can statically associate a hostname with an IP 
address. You can also view hostnames that have been learned dynamically 
through applications that use the DNS lookup service.

If you configure a static hostname and IP address, and that same hostname IP 
address mapping is later learned from DNS, the entry becomes dynamic and it is 
no longer saved as a static entry in the the Running Configuration. 

The Host Mapping Table lists hostnames that are statically assigned to IP 
addresses on the switch. To configure a static hostname mapping:

Click IP Configuration > Domain Name System > Host Mapping in the navigation 
window.

Click Add.

Enter a hostname from 1–255 alphanumeric characters. The hostname must begin 
with a letter.

Enter an IPv4 or IPv6 address to be associated with the hostname.
