Resolution

DNS configuration

This may indicate a non-responsive DNS server or an invalid DNS configuration. A DNS server converts a name to a numerical IP address, "www.apple.com" to "17.149.160.49", for example. You can connect to an IP address without any delay, because the need for DNS resolution is avoided. Here are four scenarios in which the symptom may occur:

  • You have specified two or more DNS servers in the Network preference pane (possibly at the direction of a network administrator or your ISP), but the first server on the list has become non-responsive, or was entered incorrectly. The delay occurs while Mac OS X waits for the first server to respond, then it goes to the next server in your list.  Make sure the addresses are entered correctly. Changing the order of DNS addresses may improve performance. If your network administrator prefers that the primary server be used, you may wish to change back to the original order after the issue is resolved with the primary server.
  • Your network may be configured to provide automatic discovery of DNS service, without needing to manually type the DNS server addresses at your computer. If you have manually typed a DNS address that is incorrect or out of date, your computer may wait for the incorrect address to respond (a "timeout") before succeeding at automatic discovery.
  • You have not specified a DNS server, and automatic discovery of the service is not provided on your network. In this scenario, you can only connect via an IP address. Web pages do not load at all via a DNS name, such as is described in Using network locations in Mac OS X.
