you need to add an "A" or CNAME reocrd to your DNS server or settings  for example to resovle to www.cwcl.com

If you want to resolve any typed address under cwcrl.com to www.cwcrl.com then you need a Wildcard Record. So you would want:

* CNAME www.cwcrl.com.

Open DNS Admin console in Windows Admin Tools.

Locate the cwcrl.com.

Right Click and select CNAME record.

Just put the name "example" and put IP address of web server.

Now example.cwcrl.com will resolve to the web server.

One more thing, On IIS, you need to add header of example to the website .

Well you can host your DNS service wherever you like if you own the Domain. But bear in mind that you will want your DNS servers to be always available really so you may find that hosting them yourself is going to be a bit tricky.

If it's not then you could potentially run the DNS Service on the webserver itself, I wouldn't particularly recommend it for a public site, but it is entirely possible. All it needs is BIND installing, firewall rules checking to ensure that Port 53 is allowed Inbound and a bit of setup for the Name Server itself.

You could always ask whoever hosts your DNS Server at the moment to just add the records, if I was correct in the assumption that you want anything typed before cwcrl.com to send off to the website then that would be the Wildcard Record mentioned earlier (*).
