Method Detail

parseNameserverAddress

public static java.net.InetSocketAddress parseNameserverAddress(java.lang.String str)

INTERNAL API

Parameters:

str - (undocumented)

Returns:

(undocumented)

getDefaultNameServers

public static scala.util.Try<scala.collection.immutable.List<java.net.InetSocketAddress>> getDefaultNameServers(ExtendedActorSystem system)

INTERNAL API Find out the default search lists that Java would use normally, e.g. when using InetAddress to resolve domains.

The default nameservers are attempted to be obtained from: jndi-dns and from sun.net.dnsResolverConfiguration as a fallback (which is expected to fail though when running on JDK9+ due to the module encapsulation of sun packages).

Based on: https://github.com/netty/netty/blob/4.1/resolver-dns/src/main/java/io/netty/resolver/dns/DefaultDnsServerAddressStreamProvider.java#L58-L146

Parameters:

system - (undocumented)

Returns:

(undocumented)
