Does anyone know if there is a way to add the actual visitor IP address and/or host name to the data collected in Google Analytics. Thanks.
You cant to that with Google analytics but there is are ways to do it.If your site is on a Apache server you by default will hav the IP address of the visitors in your hosting control my host saves upto (300 recent vistors' ip).Or the other ways to collect IP addresses of your vistors and storing it in database
for the ip do $ip=$_SERVER['REMOTE_ADDR']; for the host do $hostname = gethostbyaddr($_SERVER['REMOTE_ADDR']);
