Introduce a service-provider interface (SPI) for host name and address resolution, so that java.net.InetAddress can make use of resolvers other than the platform's built-in resolver. This new SPI allows replacing the operating system's native resolver, which is typically configured to use a combination of a local hosts file and the Domain Name System (DNS).
