How To Host Your Blog With Blogger

First you have to buy a domain name, or if you already own one then
you can just change your settings with your domain name company.

if you try to change your blogger name first it tells you
"Another blog is already hosted at this address"

Log into your account with your domain name.

click on "Set Nameservers"
select option "I want to park my domains."

click "Total DNS Control"
click on the litte pencil with paper next to "www"

it probably points to @ if you have a normal host.

change to ghs.google.com and click ok.

click the pencil/paper icon by host at the top and enter "216.239.32.21"

this will re-route your www extension to your naked domain name,
other wise the two will point to different addresses.
