cname

I am building a SaaS product. When a user signs up for an account they must select an alias for their site --------.getlaunchpoint.com. Right now I have an A record *.getlaunchpoint.com that points to the ip address server. However, with Azure I am not given an IP address. The suggested implementation is to make use of a CNAME.

I need to create a CNAME for *.getlaunchpoint.com -> getlaunchpoint.cloudapp.net

GoDaddy does not support CNAME wildcards. Searching on Google I'm getting conflicting information... is CNAME wildcard a bad practice?

I run into the same problem with Amazon EC2 if I want to make use of load balancers because you cannot tie a public IP address to an Amazon Load Balancer. Amazon also suggests the use of a CNAME.

Any help would be appreciated.
