Modified Web.config file but changes are not refelcting upon browsing the site.

I have modified by Web.config to add the following
    <ipSecurity allowUnlisted="false">
      <add ipAddress="XXX.XX.XX.XX" allowed="true"/>
  <modules runAllManagedModulesForAllRequests="true"/>

And i was able to restrict the access to only one IP.
After this i modified again and added two more IP's to the list.
Restarted IIS.
But the other two IP's are not able to access the website.

I can confirm that the changes are made to proper web.config file. Restarted IIS 3-4 times from Command prompt. Also stop and start in IIS was done.
Still unable to see my changes.

Kindly help and suggest.
