Google Adwords IP servers
We have a webshop which is accessible only in our country. We allow only certain IP's to "see" a web shop. This is done via Apache's htaccess file (allow, deny method).
The Google Adwords systems doesn't allow ads to run because it gets: http invalid response code. Bassicaly because the site is now visible for Google servers.
It is possible to get the list of Google Adwords IP server, so I can allow them in httaccess file?
