    <p>Currently I monitor my websites on their IPv4 and IPv6 addresses</p> <p>But my next website will be hosted with multiple IP Addresses. And I would like to <strong><em>monitor ALL of them</em></strong>.</p> <p>Here is my current code for dual-stack monitoring (monitoring only one IP address)</p> <pre><code>&lt;?php $resultat4 = file_get_contents_curl( 'http://www.mydomain.com/?cjg_monitoring=1', 4); $resultat6 = file_get_contents_curl( 'http://www.mydomain.com/?cjg_monitoring=1', 6); if (substr($resultat4,0,2) == "OK"){ echo 'IPv4 stack OK' } if (substr($resultat6,0,2) == "OK"){ echo 'IPv6 stack OK' } function file_get_contents_curl($url,$ip_version=0) { $ch = curl_init(); if($ip_version == 4) curl_setopt($ch, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4 ); elseif($ip_version == 6) curl_setopt($ch, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V6 ); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); //Set curl to return the data instead of printing it to the browser. curl_setopt($ch, CURLOPT_URL, $url); $data = curl_exec($ch); curl_close($ch); return $data; } ?&gt; </code></pre> <p>How could I get all the IP addresses tested with Curl PHP ?</p> <p>What I would like to do would be similar to this simpler version:</p> <pre><code>&lt;?php $ip_adds = get_all_ip_addresses( $url ); $problem_encountered = false; foreach( $ip_adds as $ip_add ){ $content = get_content_url_on_ip( 'http://www.mydomain.com/?cjg_monitoring=1', $ip_add ); if ( $content != "OK") $problem_encountered = true; } if ( !$problem_encountered ) echo "All IPv4 and IPv6 Addresses OK"; ?&gt; </code></pre> <p>in my case www.mydomain.com has many ip addresses of each version:</p> <pre><code>$host www.mydomain.com www.mydomain.com has address 173.194.35.180 www.mydomain.com has address 173.194.35.176 www.mydomain.com has address 173.194.35.177 www.mydomain.com has IPv6 address 2001:db8:4016:801::1008 www.mydomain.com has IPv6 address 2001:db8:4016:801::1009 www.mydomain.com has IPv6 address 2001:db8:4016:801::1010 </code></pre> <p>Which is why I use this :</p> <pre><code> //return array[0][ip] or array[0][ipv6] function get_all_ip_addresses( $url ){ $url_tab = parse_url($url); $host = $url_tab['host'] $ip4s = dns_get_record($host, DNS_A); $ip6s = dns_get_record($host, DNS_AAAA); return array_merge($ip4s, $ip6s); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
