The code snippet below will detect the visitor’s IP address and check against the IP address you don’t want accessing your website; if the addresses match, then our visitor will be redirected to the page “no_access.asp”.

Dim sBlockedIP
sBlockedIP = Request.ServerVariables("REMOTE_ADDR")
'check if the IP is the one that is blocked
If sBlockedIP = "127.0.0.1" Then
'if IP address is banned then redirect to no_access.asp
Response.Redirect "no_access.asp"
End If
