I read several previous discussion posts on the Domain Mapping plugin and subdomains, but the situations I found don't seem to be the same as mine... I apologize if I've missed something obvious.
I have a network of WordPress sites on seventh-star.net. One of those sites is mapped (using the Domain Mapping plugin) to meredithsweet.com. All is well.
What do I do if I want to create a NEW site that has the URL blog.meredithsweet.com?
When I go to Add a Site in my Network, it assumes I want the URL to include "seventh-star.net," since that's the primary domain. Is there a way to get it to be meredithsweet.com for this one use, or is there a way to set it up so it gives me a choice?
In trying to figure this out, I've looked into what I already have setup for the meredithsweet.com domain: it's set up as an Alias (that doesn't redirect anywhere; it has the domain root of my public_html, which I think is similar to the wildcard for the seventh-star.net sites?), and I have several CNAME and A records relating to it, though I'm not 100% sure of what all of them do.
Would it be as easy as creating a CNAME record for blog.meredithsweet.com, and somehow making sure it directs to a WordPress site on the Network? How do I add the site without creating an extra URL, e.g. blog.seventh-star.net?
