Until recently you couldn't take advantage of Adsense for Domains if you registered a domain name with Fasthosts. However, with the new Fasthosts control panel which now allows you to edit DNS settings, domain name owners can now earn revenue from domain names they don't currently use.
If you're familiar with Google Adsense, you may have seen the "Adsense for Domains" link on the "Adsense Setup" tab on the Adsense navigation. Unfortunately the "Quick start guide" Google provides doesn't include instructions for Fasthosts setup and following the generic instructions doesn’t work either.
Log-in to your Fasthosts control panel and click on the “DNS” button for the domain you wish to use to park with Adsense for Domains.
Find your "unique identifier" from the Adsense for Domains page within Adsense and create a CNAME as follows:
Host Name: www
Points to: your adsense unique identifier e.g pub-xxxxxxxxxxxxxxafd.ghs.google.com.
Next create an A record as follows:
Host Name: leave blank
Points to: 22.214.171.124
See the screenshot below for a finished example…
