/**
 * Allows network access when using the  {@link LessIOSecurityManager}.
 *
 * {@link #endpoints()} is the list of allowed IP endpoints (both local and remote)
 * in [hostname]:[port] format. [hostname] and/or [port] may be "*",
 * indicating that accessing any hostname, or port, is allowed.
 *
 * Port may be 0, which indicates that connections may be made to ephemeral ports.
 *
 * Note that due to performance restrictions, the {@link LessIOSecurityManager}
 * only performs textual matches, and does not resolve hostnames or IP
 * addresses.

 * @see LessIO Wiki, @AllowNetworkAccess.
