Hi xxxxx,
Thanks for your email. Please rest assured there's no need to create a new
AdSense account in order to switch your IP address.
In case you're worried about the possibility of invalid clicks being
generated on your site, I've provided a couple of solutions below which
will hopefully address your concerns.
1. First, you can feel free to review your site's traffic logs for
suspicious activity and notify us with any findings. This information can
help us in resolving any issues, although as we've noted in our Terms and
Conditions, Google will use its sole discretion when determining instances
of invalid clicks. If you need help logging the traffic on your site,
please try these Google search terms:
Webmaster resources
Website tracking and logging
Site traffic analysis
If you'd like to notify us of your findings, please visit
https://www.google.com/support...contact=invalid_clicks_contact 
.
You can find tips and guidelines for keeping your account in good standing
by visiting our Help Center at
https://www.google.com/support...nse/bin/answer.py?answer=23921 
.
2. Also, a good way to ensure that you do not generate invalid clicks is
by reviewing and remaining in compliance with our Terms and Conditions and
program policies:
https://www.google.com/adsense/terms
https://www.google.com/adsense/policies 
Finally, please allow me to give you some quick context on the issue. In
order to protect your interests as well as those of our advertisers,
Google monitors clicks on Google ads to prevent any abuse of the AdSense
program. To do this, we use both automated systems and human reviews. More
specifically, our technology analyzes all ad clicks for any invalid click
activity that is intended to artificially drive up an advertiser's clicks
or a publisher's earnings.
For additional questions, I'd encourage you to visit the AdSense Help
Center (
http://www.google.com/adsense_help 
), our complete resource center
for all AdSense topics. Alternatively, feel free to post your question on
the forum just for AdSense publishers: the AdSense Help Group
(
http://groups.google.com/group/adsense-help 
).
Sincerely,
Laura
The Google AdSense Team
