Example 21 with Inet6Address

use of java.net.Inet6Address in project cassandra by apache.

the class DatabaseDescriptorTest method selectSuitableInterface.

     * Server only accepts interfaces by name if they have a single address
     * OS X seems to always have an ipv4 and ipv6 address on all interfaces which means some tests fail
     * if not checked for and skipped
