some questions about my ASP ad/click tracker

I have a clicktracker for my website that keeps track of when banners in certain spots on my site are clicked.

The site was re-done for me in ASP back in October. I am not a coder but I do my best to get around.

The problem I have is that pretty much every day I load a report I see multiple clicks from the same IP address all at the same time. What would be causing this type of clicking? Is there something wrong with the clicktracker or are there automatic bot/spider type things that come through and repeatedly click banners? Here is an example:

CLICK # DATE CLICKED IP ADDRESS AD #
1418 4/1/2008 0:36 124.181.217.139 135
1419 4/2/2008 19:07 212.106.154.2 109
1420 4/2/2008 19:08 212.106.154.2 96

1422 4/2/2008 19:08 212.106.154.2 110
1423 4/2/2008 19:08 212.106.154.2 107
1424 4/2/2008 19:08 212.106.154.2 76
1425 4/2/2008 19:08 212.106.154.2 111
1426 4/2/2008 19:08 212.106.154.2 138

I have copied the adtracker code below. If anyone could look through it and offer up why I might be getting the strange results I would appreciate it. Let me know if you need to see more of the code and I will do my best to find it.

<%@language=vbscript%>
<%if not isnumeric(request("siteid")) then response.redirect "/default.asp"%>
<%siteid=abs(request("siteid"))%>

<!--#include virtual="/includes/connx.asp"-->

<%
'open ads record
set ads = Server.CreateObject("ADODB.Recordset")
sql="SELECT top 1 * from ads where id="&siteid&" "
ads.Open sql,dconn
if ads.eof and ads.bof then
response.redirect "/default.asp"
else ''''' AD IN DATABASE, RECORD CLICK AND REDIRECT!!!
datenow=now()
ipaddress=request.servervariables("remote_addr")
sql = "insert into clicktracker (dateclicked,ipaddress,adid) values ('"&datenow&"','"&ipaddress&"',"&siteid&")"
dconn.execute sql
response.redirect ads("url")
end if
ads.close
set ads=nothing
dconn.close
set dconn=nothing
%>

Here is some more code that might be of use

<div class="center"><%

commacount=0
for i = 1 to len(cms("adstorotate"))
if mid(cms("adstorotate"),i,1)="," then commacount=commacount+1
next

if taglist<>"" then
'open buttons ad record
set had = Server.CreateObject("ADODB.Recordset")
if adlist="" then
sql="SELECT top 1 * from ads where adstyle='ab' and tagline IN ("&taglist&") order by newid()"
else
if commacount>1 then
sql="SELECT top 1 * from ads where adstyle='ab' and tagline IN ("&taglist&") order by newid()"
else
sql="SELECT top 1 * from ads where tagline not in ("&adlist&") and adstyle='ab' and tagline IN ("&taglist&") order by newid()"
end if
end if
had.Open sql,dconn
if had.eof and had.bof then
else
picurl="../editor/assets/ad_images/" & had("filename")
if had("windowstyle")=1 then%>
<a href="/adtracker/?siteid=<%=had("id")%>" target="_blank"><img alt="<%=had("tagline")%>" src="<%=picurl%>"></a>
<%else%>
<a href="/adtracker/?siteid=<%=had("id")%>"><img alt="Advertisement" src="<%=picurl%>"></a>
<%end if%><%

if adlist<>"" then
adlist=adlist & ",'" & had("tagline")&"'"
else
adlist="'" & had("tagline") & "'"
end if ' adlist check
end if
had.close
set had=nothing
end if ' taglist empty check
%>
</div>

Normal first thing is to do a whois on the IP and see if you have any knowledge of the owner. The second element is to look at the server logs for the requests and see what the user agent is (eg IE, FireFox, GoogleBot etc)

 

Okay now here is the wierd thing about that!

Some of the IP addresses showing up in my clicktracker cannot be found in my log!

This is with extensive searching through and through.

I have been able to pull up info on one of the suspect IP's but most of them cannot be found in my log. Here is the info I just found on one of them:

Referring Link No referring link
Host Name 59.208.62.58.broad.gz.gd.dynamic.163data.com.cn

I would have thought the Google-Bot, but this sounds wierd...
