WordPress MU Domain Mapping
CNAMES for TLDs (3 posts)

    Can you let us know what we need to advise users about how to CNAME their top level domain to their multisite blog? CNAMES, as I understand them, are only meant to be used in conjunction with subdomains. In other words, you can't CNAME topleveldomain.com. But you can CNAME subdomain.topleveldomain.com.

    So what if a user wants to map mydomain.com to their multisite blog? Sure, they can modify the CNAME for http://www.topleveldomain.com. But what about traffic without the www? Someone suggested forwarding that traffic to the www variant of the domain, which is then mapped to the multisite blog. But that seems like a lot of setup that users will find confusing, not to mention a lot of redirecting.

    What should we tell users about setting up a CNAME for their TLD?

    It depends on the registrar whether you can use a CNAME with a TLD.

    Also, http://www.domain.com is not a TLD. The www is a subdomain.

    Hi Ron,

    Also, http://www.domain.com is not a TLD. The www is a subdomain.

    I know. I was just saying that, in situations where the user can't CNAME the TLD, doing so for the www subdomain might be the way to go.

    Upon further research, I found out that this is exactly how cPanel thinks. If a user CNAMES the www subdomain to a mapped domain, cPanel understands that the user is wanting to redirect the web traffic to that domain. And it seems to automatically forward the non-www traffic there as well without the need for the user to set up a redirect for that.

    BTW, thanks you you and Andrea for everything you do. I've been helped many times by your advice in various places on the net.
