You need to make sure you have the following settings EXACTLY as shown below. Either do this yourself in your DNS control panel of the company where your Domain is registered or contact their support and ask them to do it for you.
NOTE: Replace yourdomain with your actual domain
For Posterous blogging
yourdomain.com. 300 IN A 220.127.116.11
There is no need to change the DNS here.
yourdomain.com. 300 IN A 18.104.22.168
yourdomain.com. 300 IN A 22.214.171.124
yourdomain.com. 300 IN A 126.96.36.199
yourdomain.com. 300 IN A 188.8.131.52
www.yourdomain.com. 300 IN CNAME ghs.google.com.
Once you have made the corrections, try your Custom Domain again by doing the following.
1) Goto to Settings, Publishing and click the Switch To Blogspot link and save the changes. (This step may not be necessary if you have not already tried to use your Custom Domain)
2) Then once saved go back to Settings, Publishing and click the Custom Domain link, then click Advanced Settings link, and put your domain in www.yourdomain.com (lowercase) and save your changes.
3) On this screen make sure you click the Re-Direct check box.
Explained again: For blogger
- Find the control panel on your domain registrar’s website, and locate your DNS (Domain Name System) settings. In order to link your blog to your custom domain, follow the instructions below to enter your "CNAME" and "A-records."
Where it says Name, simply enter "www" and list ghs.google.com as the Host Name. See our detailed instructions on providing CNAMEs for various registrars. If yours isn't listed, or if you run into other difficulties, contact your registrar directly and they can help you out.
The following action links your naked domain (example.com) to your actual site (www.example.com). If you skip this step, visitors who leave off the "www" will see an error page.
Enter your domain name in the format example.com, and list the I.P. addresses shown below in the "A" section. You'll need to create four separate A-records which point to four different Google IPs.
- Update your Blogger settings
Before you move onto this step, wait about an hour for your DNS settings to activate. If you attempt to change the publishing settings before the DNS changes activate, then we'll let you know with a warning message.
Now it’s time to make sure Blogger knows about your custom domain so that Google can direct readers to your blog. Just head back to Blogger and update the information on your Settings | Basic tab. Find the area for "Publishing," and click the link to add a custom domain.
Then, click on "Switch to advanced settings." Enter in the URL for your custom domain in the text box provided, and click Save. That’s it! Your blogspot.com address will soon redirect to your new custom domain -- be patient, as it might take up to 24 hours for the redirect to start working. Congratulations, you’re all set!
Some helpful notes:
- If your new domain isn't taking you to your blog, wait another day or two to make sure all the DNS servers have been updated. If it still isn't working, contact your registrar to make sure you entered the DNS settings correctly.
- Your original Blogspot address will automatically forward to your new domain. That way, any existing links or bookmarks to your site will still work.
- Your posted images will continue to display on your blog.
