Mapping subdomain using different nameserver

    I am trying to move my Blogger blog to a blog in my WordPress Multisite installation. I have imported the blog, and my multisite installation works fine, but I am having problems getting my domain mapping to work. Here’s my configuration (not real domain names):

    1. Multisite install is on Hostgator.
    2. The following domains are registered with GoDaddy and have nameservers set to Hostgator: multisiteparent.com, examplesite.com
    3. examplesite is currently configured as a parked domain with Hostgator and mapped to one of the sites in my multisite install without issue.
    4. The following domains are registered with GoDaddy and use GoDaddy nameserver: mainsite.com. This address redirects to my photo website hosted by Smugmug.

    Currently, blog.mainsite.com is configured to point to my Blogger blog. But I want to change it to point to photoblog.multisiteparent.com (i.e. a site in my multisite installation).

    So far I have:

    1. Added blog.mainsite.com domain mapping and set it as primary domain on photoblog.multisiteparent.com
    2. Added a CName entry in GoDaddy config host: blog, points to: photoblog.multisiteparent.com

    I thought that would do it, but now when I go to blog.mainsite.com (or photoblog.multisiteparent.com) I get a Hostgator 404 error.

    I contacted Hostgator support, and they told me that this sub-domain mapping would not work because I was using multisite installation and mainsite.com was using GoDaddy’s nameservers. If I wanted to use this configuration, I would have to create a separate WP installation to get the mapping to work.

    Is the Hostgator support tech right that it’s impossible? Is there something I can do to get this working?

    Thanks!

    Hey Danny,

    There is some crazy amount of information in this post! 🙂

    Added blog.mainsite.com domain mapping and set it as primary domain on photoblog.multisiteparent.com

    This is correct.

    Added a CName entry in GoDaddy config host: blog, points to: photoblog.multisiteparent.com

    This is never going to work, as this is the zone of a totally different domain name. (I keep wondering how you were able to do it, unless it actually points to photoblog.multisiteparent.com.mainsite.com, but anyway..)

    What you basically need to do is:

    1) Add an A record for the blog mainsite com subdomain in the mainsite com zone in the GoDaddy nameservers pointing to the IP of the web server that hosts your multisite (at Hostgator).

    2) Add an A record for the photoblog multisiteparent com in the multisiteparent com zone in the Hostgator nameservers pointing to the same IP as blog mainsite com above.

    3) Make sure the web server at Hostgator is configured to serve both blog mainsite com and photoblog multisiteparent com.

    4) Make sure the domain mapping at the multisite is blog mainsite com —> photoblog multisiteparent com. (You have probably already done this one).

    I think that’s all. Hope I got it right.

    Thanks George!

    I really appreciate the reply. As you can probably guess, I’m pretty new to configuring these things (when I set things up with my Smugmug accound they had very specific instructions and I didn’t have to figure anything out on my own :-)).

    The strange part was with the IP addresses. I had two different ones 1) The one from Hostgator CPanel 2) The one listed in the domain mapping plugin. When I configure the A record on GoDaddy, I had to use the IP given by the plugin. When I added the A record in Hostgator, I used the CPanel IP.

    Anyway, I got it working now thanks again!
