I have a domain with a wildcard subdomain entry pointed at IP-A:
domain-a.com -> xxx.xxx.xxx.xxx
*.domain-a.com -> xxx.xxx.xxx.xxx
Can I create another CNAME pointing a spcified subdomain at a different IP. Or, rather, if I create such an entry, will it resolve to the 2nd IP?:
domain-a.com -> xxx.xxx.xxx.xxx
*.domain-a.com -> xxx.xxx.xxx.xxx
thing.domain-a.com -> yyy.yyy.yyy.yyy
Will that work? Does it even make sense?
Yes. See RFC 1034, section 4.3.3 for more technical information.
