Configure Eucalyptus DNS

Eucalyptus provides a DNS service that maps service names, bucket names, and more to IP addresses. This section details how to configure the Eucalyptus DNS service.

Important: Eucalyptus administration tools are designed to work with DNS-enabled clouds, so configuring this service is highly recommended. The remainder of this guide is written with the assumption that your cloud is DNS-enabled.

The DNS service will automatically try to bind to port 53. If port 53 cannot be used, DNS will be disabled. Typically, other system services like dnsmasq are configured to run on port 53. To use the Eucalyptus DNS service, you must disable these services.
