DNS
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.
Overview
DNS:
• Is used to resolve the host’s IP address
• Enables a static host name entry to be used to resolve the IP address
Examples
The following are examples of how the DNS feature is used.
Example 1#: 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.
