All Implemented Interfaces:

Closeable, AutoCloseable
```
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.

Modifier and Type	Method	Description
`protected AddressResolver<InetSocketAddress>`	`newAddressResolver(EventLoop eventLoop, NameResolver<InetAddress> resolver)`	We need to override this method, not `DnsAddressResolverGroup.newNameResolver(EventLoop, ChannelFactory, DnsServerAddressStreamProvider)`, because we need to eliminate possible caching of `NameResolver.resolve(java.lang.String)` by `InflightNameResolver` created in `DnsAddressResolverGroup.newResolver(EventLoop, ChannelFactory, DnsServerAddressStreamProvider)`.
