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

resolve

                                          ActorSystem system,
                                          ActorRef sender)

Deprecated.

Use resolve(DnsProtocol.Resolve). Since Akka 2.6.0.

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