I am running a blog at posterous.com, and they can host my domain name if I create an A record to their IP in my domain registrar's custom DNS tool.
The problem is that I want my domain to ALWAYS read domain.com, so I want to have my DNS remap any requests to www.domain.com to domain.com, and I can't use .htaccess or PHP or other server methods, since it's just a blog interface.
So far, I've tried:
@ A target.ip.address www CNAME domain.com
Which redirects www.domain.com to the right site, but the www. is still on the domain. I heard you could do:
@ A target.ip.address www A internal.redirector.ip.address
but I don't know my registrar's internal IP address that might handle this redirection (or even if such a thing actually exists).
Can what I'm asking for be done?
Thanks, you guys rock.
