If you already own a custom domain name, you can use it for your OverBlog.
Before changing the domain name for your Page though, you need to properly set the CNAME value in your registrar control panel. Please set the CNAME value to “vip.over-blog-kiwi.com.”.
Then go to Settings > Domain name and enter you domain name.
It might then take from 3 to 24 hours for the DNS to be updated and the changes to be effective.
Note that if you set a new domain name before configuring the CNAME value, your Page will be inaccessible.
Should you have trouble following these steps, we suggest you either leave it as it is or subscribe to OverBlog Premium to have your own customised domain name.
