DNSStuff IP Lookup no longer working?

i've noticed that lately when i click on an IP address on the who's online page that the website DNSSTUFF.com now requires a customer login to access their IP lookup tool.

is it possible to code this link to populate IP information into another lookup site??

nevermind... i found it.

/admin/whos_online.php

line #304

currently states:

<td class="dataTableContentWhois" align="left"><a href="http://www.dnsstuff.com/tools/whois.ch?ip=<?php echo $whos_online->fields['ip_address']; ?>" target="new"><?php echo '<u>' . $whos_online->fields['ip_address'] . '</u>'; ?></a></td>

can be changed to:

<td class="dataTableContentWhois" align="left"><a href="http://whois.domaintools.com/<?php echo $whos_online->fields['ip_address']; ?>" target="new"><?php echo '<u>' . $whos_online->fields['ip_address'] . '</u>'; ?></a></td>

works very nicely.

Or you can replace it by this and still use the dnsstuff.com free service

<td class="dataTableContentWhois" align="left"><a href="http://www.dnsstuff.com/tools/ipall/?tool_id=67&token=&toolhandler_redirect=0&ip=<?php echo $whos_online->fields['ip_address']; ?>" target="new"><?php echo '<u>' . $whos_online->fields['ip_address'] . '</u>'; ?></a></td>
