10   *
11   * ``` js
12   * isInNet(host, "198.95.249.79", "255.255.255.255")
13   *   // is true iff the IP address of host matches exactly 198.95.249.79.
14   *
15   * isInNet(host, "198.95.0.0", "255.255.0.0")
16   *   // is true iff the IP address of the host matches 198.95.*.*.
17   * ```
18   *
19   * @param {String} host a DNS hostname, or IP address. If a hostname is passed,
20   *   it will be resoved into an IP address by this function.
21   * @param {String} pattern an IP address pattern in the dot-separated format mask.
22   * @param {String} mask for the IP address pattern informing which parts of the
23   *   IP address should be matched against. 0 means ignore, 255 means match.
24   * @return {Boolean}
