Using * alongside subdomains

I have a domain being pointed to by web server.

I'm no expert but I normally create a * record and point that to the IP.

In this case however the customer has mail. and docs. subdomains.

Will pointing the star effect that?

Thanks

The star is a wildcard designation. If you use a * to point to the IP, then it will already encompass any subdomain you had in mind (mail, docs, www, etc...)

So in noob terms

docs. wont then work because it will all be caught by the *

Is that right?

If you set up your DNS to use wildcards, then assigning * to 68.222.222.22 would make it so that any of the subdomains would work provided there is a virtual host or something similar set up to route the subdomains somewhere.

If set up properly, docs.domain.com, mail.domain.com, www.domain.com, subdomain.domain.com, etc, would all work.

You would use your web server (Apache, IIS, etc..) to designate where the subdomains went.

Ok cheers.

I think I've got it.
