I am using a subdomain as a parameter to an ASP.NET MVC 4 application. It's working well.

Now I need to test my approach, so I have the application hosted on appharbor. It works well with subdomains here too. Our DNS registers are on Rackspace, but I have no control over it. Another guy is responsible for that. So, can be accessed through Also is working as expected. I use abc as a parameter.

So, now I want to be mapped in those Rackspace DNS registers to

Is this possible at all? Can you explain to us how to do that? Will I have some problems with it? Anything that I should be aware of?

Please have in mind that I am newbie when it comes to DNS. And no experience with Rackspace.

If "Another guy is responsible for that" then ask him to figure it out! –  dunxd Dec 12 '12 at 11:58
It was my idea for this kind of approach. It's complicated to explain... Anyway, if you can answer me the questions, regardless who is responsible, it would be great. Those are my concerns :) –  Gorgi Rankovski Dec 12 '12 at 12:57

You could use a CNAME to point (or a sub-domain, wildcard or @ record of to the host

Or you could set up an A record for (or a sub-domain, wildcard or @ record of to the IP address of the host

Of course you have to make sure that the host will handle requests made to once it start receiving them.
