I have this kind of settings for Google Sites and Blogger in Godaddy, below. I cannot get URL Framing (not URL masking) working with them. I am unsure what the problem, cannot understand what services such as Blogger and Godaddy really do.

Wrong A-records in Go Daddy!

1. Please, explain the "Custom Domain" and how can I hide my blogger url?
2. ok I am still unsure what the "custom domain" in blogger really mean, does it mean that the content hosting is moved to some other site?
3. Or does it mean that it just hides the blogspot url with other url?
4. Or is it this so-called "301" thing or "URL redirection" or something else?
