cached

public scala.Option<Dns.Resolved> cached(java.lang.String name)

Deprecated.

Use cached(DnsProtocol.Resolve). Since 2.6.0.

Lookup if a DNS resolved is cached. The exact behavior of caching will depend on the akka.actor.io.dns.resolver that is configured.

resolve

public scala.Option<Dns.Resolved> resolve(java.lang.String name,
                                          ActorSystem system,
                                          ActorRef sender)

Deprecated.

Use resolve(DnsProtocol.Resolve). Since 2.6.0.

If an entry is cached return it immediately. If it is not then trigger a resolve and return None.
