21. DNS Domain Name System 21 This chapter provides the following examples: • Specify Two DNS Servers • Manually Add a Host Name and an IP Address on page 379 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. CLI: Specify Two DNS Servers (Netgear Switch)#config (Netgear Switch) (Config)#ip name-server 12.7.210.170 219.141.140.10 (Netgear Switch) (Config)#ip domain-lookup (Netgear Switch) (Config)#exit (Netgear Switch)#ping www.netgear.com Send count=3, Receive count=3 from 206.82.202.46 Web Interface: Specify Two DNS Servers 1.
