Re: IP exclusion?
About the only way to find IP addresses is by going through your web logs. Assuming you have auto-tagging enabled, looking for the opresence of a gclid value in the query string is the most reliable method of identifying AdWords clicks.
The IP exclusion has moved! (Nice of them to tell us about it, huh?) You will now find it under the networks tab in the "Exclusions".
Best of Luck!
