@UnstableApi
public class RoundRobinDnsAddressResolverGroup
extends DnsAddressResolverGroup

A AddressResolverGroup of DnsNameResolvers that supports random selection of destination addresses if multiple are provided by the nameserver. This is ideal for use in applications that use a pool of connections, for which connecting to a single resolved address would be inefficient.
