Configuring Domain Name System Servers

The Domain Name System (DNS) resolver is a feature in a Layer 3 device that sends and receives queries to and from the DNS server on behalf of a client. You can configure the RUCKUS device to recognize DNS servers. You can configure only up to four IPv4 server addresses and four IPv6 server addresses. The first entry serves as the default primary address. If a query to the primary address fails to be resolved after three attempts, the next DNS address is queried (also up to three times). This process continues for each defined DNS address until the query is resolved. The order in which the default DNS addresses are polled is the same as the order in which you enter them.

Complete the following steps to configure DNS servers.

  1. Select Management > DNS Server.
    All DNS server address information displays for the IPv4 DNS servers and the IPv6 DNS servers.
