/**

 * Provides the implementation of the DNS Java Naming provider.

 *

 * <h2>Environment Properties</h2>

 *

 * <p> The following JNDI environment properties may be used when creating

 * the initial context.

 *

 * <ul>

 *    <li>com.sun.jndi.dns.timeout.initial</li>

 *    <li>com.sun.jndi.dns.timeout.retries</li>

 *  </ul>

 *

 * <p> These properties are used to alter the timeout-related defaults that the

 * DNS provider uses when submitting queries. The DNS provider submits queries

 * using the following exponential backoff algorithm. The provider submits a

 * query to a DNS server and waits for a response to arrive within a timeout

 * period (1 second by default). If it receives no response within the timeout

 * period, it queries the next server, and so on. If the provider receives no

 * response from any server, it doubles the timeout period and repeats the

 * process of submitting the query to each server, up to a maximum number of

 * retries (4 by default).

 *

 * <p> The {@code com.sun.jndi.dns.timeout.initial} property, if set, specifies

 * the number of milliseconds to use as the initial timeout period (i.e., before

 * any doubling). If this property has not been set, the default initial timeout

 * is 1000 milliseconds.

 *

 * <p> The {@code com.sun.jndi.dns.timeout.retries} property, if set, specifies

 * the number of times to retry each server using the exponential backoff

 * algorithm described previously. If this property has not been set, the

 * default number of retries is 4.

 *

 * @provides javax.naming.spi.InitialContextFactory

 *

 * @moduleGraph

 * @since 9
