NETGEAR Managed Switches Software Administration Manual, Release 8.0 Chapter 21 DNS In this chapter, the following examples are provided: • "Specify Two DNS Servers" • "Manually Add a Host Name and an IP Address" on page 21-2 This section describes the Domain Name System (DNS) feature.

You can obtain the DNS server IP address from your ISP or public DNS server list.
