Hi, this is very simple...

I am trying to find out if an IP address (that was saved in a table) is in a particular column called IP and if that is so...return a result

I just need the SQL to get it done

ADO connection here to whatever .mdb

i need the sql to determine whether or not the value is in the table or not...or at least how to find out ... evaluate and send a result bsed on that

i will take the result and then redirect all IP's in the list to a page prohibiting them from entering the site...

basically i just need a snipplet of how to check if the IP in already in the DB or not

Looking for something like this?
'Datebase connection
set oConn=Server.CreateObject("ADODB.Connection")
oConn.Provider="Microsoft.Jet.OLEDB.4.0"
oConn.Open "Database.mdb" 'CHANGE DATABASE NAME!
set oRS = Server.CreateObject("ADODB.recordset")
sql="SELECT IP FROM Table1" 'CHANGE TABLE NAME!
oRS.Open sql, oConn
 
If oRS.EOF Then
	'IP Not Found!
Else
	Response.Redirect("http://www.google.com/")
End If
 
'Cleanup
oRS = Nothing
oConn = Nothing
oRS.Close
oConn.Close

dim rs as recordset
set rs =currentdb.openRecordset("SELECT * FROM IP WHERE IP_COLUMN = ' " & sIPVariable & " ' "
if rs.eof then
'not in table
else
'in table
end if

DarrenMcCall,
- There is no condition in your query, so it will just check if there is anything in the table or not.
- If you do a redirect before the cleanup, the cleanup will not run.
- In the cleanup, you have to call Close before you set the references to Nothing.

This will work a little bit better:
' Declare variables
Dim objConnection, objRS, lngCnt, strIP
' Get IP
strIP = Request.ServerVariables("REMOTE_ADDR")
' Open connection
Set objConnection = Server.CreateObject("ADODB.Connection")
objConnection.Provider = "Microsoft.Jet.OLEDB.4.0"
objConnection.Open "Database.mdb"
' Count occurances of the IP
strSQL="select count(*) from Blocked where IP = '" & Replace(strIP, "'","''") & "'"
Set objRS = objConnection.Execute(strSQL)
' Get the result
lngCnt = objRS(0)
' Close the recordset
objRS.Close
Set objRS = Nothing
' Close connection
objConnection.Close
Set objConnection = Nothing
' Check result
If lngCnt = 0 Then
        'IP Not Found
Else
        Response.Redirect "Denied.asp"
End If

this is the snipplet of code that I developed to achieve this task.  
Dim adoCon, ID, rsGuestbook, strSQL, banIP
Set adoCon = Server.CreateObject("ADODB.Connection")
adoCon.Open "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=" & Server.MapPath("guestbook_2003.mdb")
Set rsGuestbook = Server.CreateObject("ADODB.Recordset")
strSQL = "SELECT Banned.IP FROM Banned WHERE IP='" & Request.ServerVariables("REMOTE_ADDR") & "'"
rsGuestbook.Open strSQL, adoCon
 
Do While not rsGuestbook.EOF
	banIP = rsGuestbook("IP")
	if banIP <> "" then
	Response.Redirect "Denied.asp"
	end if
	rsGuestbook.MoveNext
loop
 
rsGuestbook.Close
Set rsGuestbook = Nothing
Set adoCon = Nothing
