Hope you dont mind me adding this bit of info.
In
whosonlinbit
find
Code:
<a href="online.php?$session[sessionurl]do=resolveip&ipaddress=$userinfo[host_encoded]" id="resolveip_$count" title="$vbphrase[resolve_ip_address]">$userinfo[host]</a>
<else />
$userinfo[host]
Replace with
Code:
<a target="_blank" href="http://whois.domaintools.com/$userinfo[host]">$userinfo[host]</a>
I used the Domain Toos Url just because I like it better. Otherwise just the same code given in the zip file
