Wildcard A record not resolving to main domain [RESOLVED]

I have four domains. Each has a * A record. Example for one domain below. I would expect that going to any subdomain other than blog should resolve to benmillett.us. However, any (fake) subdomain for any four of my domains resolves to agifforyou.com, which is the first domain alphabetically. I can set up .htaccess rules to redirect for each site, but I thought that DNS * A record was supposed to take care of that. What am I missing?
