This chapter provides the following examples:
•

Specify Two DNS Servers

• Manually Add a Host Name and an IP Address
This section describes the Domain Name System (DNS) feature. The DNS protocol maps a host
name to an IP address, allowing you to replace the IP address with the host name for IP
commands such as a ping and a traceroute, and for features such as RADIUS, DHCP relay,
SNTP, SNMP, TFTP, SYSLOG, and UDP relay.
You can obtain the DNS server IP address from your ISP or public DNS server list. DNS is used
to resolve the host's IP address. It enables a static host name entry to be used to resolve the IP
address. The following are examples of how the DNS feature is used.
Specify Two DNS Servers
The following example shows how to specify two DNS servers (that is, two IP addresses for
DNS servers) and to resolve an IP address using the DNS server. The example is shown as
CLI commands and as a Web interface procedure.
