Hope you dont mind! I got this to work with 4.0.x The coding is probably wrong but it still works for me.
In
whosonlinbit
find
Code:
<a href="online.php?{vb:raw session.sessionurl}do=resolveip&ipaddress={vb:raw userinfo.host_encoded}" id="resolveip_{vb:raw count}" title="{vb:rawphrase resolve_ip_address}">{vb:raw userinfo.host}</a>
Replace with
Code:
<a target="_blank" href="http://www.dnsstuff.com/tools/ipall.ch?domain={vb:raw userinfo.host}&submit=Search+WHOIS">{vb:raw userinfo.host}</a>
