The logic may need to be "find the parent NET HANDLE for the most specific (or least specific) of my networks". I guess most specific is the proper logic, but I could easily be wrong about that. Another option to help solve that problem might be to return ALL the net handles for each network registered by a registrant given an IP. Because it is possible for a single API Key to have an authorization over multiple organizations, that query would also need to include an ORG Handle.

Something like this works just fine, however, if you have DESWIPPED make sure you set a 600 second timer for the whois database to update before you SWIP again otherwise you will match the block that no longer exists while waiting for whois to update.


  // Perform the transaction via cURL
  $ch = curl_init();
  $url = ARIN_WHOIS_URL . "/ip/" . $params['net_block']['address'];
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_TIMEOUT, 4);
  curl_setopt($ch, CURLOPT_HTTPHEADER, 0);
  if (!$debug) curl_setopt($ch, CURLOPT_MUTE, 1);

  $retval = curl_exec($ch);
  if ($debug) echo $retval;

  $info = curl_getinfo($ch);

  $response = "";
  if ($retval == false) {
    $res = "Failure:Get Parent Network:Could not connect. <br />";
    $response .= $res;
  else if ($info['http_code'] != 200) {
    $res = "Failure:Get Parent Network:Return code is " . (int)($info['http_code']) . "<br />";
    $response .= $res;
  else {
    $res = "Success";
    $response .= $res;
    $response .= $retval;
