Connection string using dns name

I read an article about how to use dns alias instead of server names in teh connection strings. but in the article the use a name like instead of SERVERA you could use SQLPROD.

My question is that will a connection string use a full FQDN DNS name like sqlprod.contoso.com  ?

In the article they specified another name which is not neccessary a dns alias,  it would probably still use wins first.

Thanks.
