Setup wildcard subdomain with Bind

I found a good documentation about configuring a DNS server to use wildcard domains for development: http://superrb.com/blog/2012/09/24/how-to-set-up-bind-on-ubuntu-for-a-wildcard-development-domain

All went well in my setup, I just have to adapt some paths and made use of bind conventions described in arch wiki.

All well, except the fundamental: wildcard subdomain. After googling a bit and read some similar questions in stackoverflow this was my final configuration:

• /etc/named.conf

zone "dev.com" {
        type master;
        file "dev.com.zone";
};

•  /var/named/dev.com.zone

;
; BIND data file for local loopback interface
;
$TTL 14400
@ IN  SOA dev.com. root.dev.com. (
            2014110801   ; Serial
                 86400   ; Refresh
                  7200   ; Retry
               3600000   ; Expire
                 86400 ) ; Negative Cache TTL
;
@ IN  NS  dev.com.
@ IN  A 127.0.0.1
* IN  CNAME dev.com.
@ IN  AAAA  ::1

If you don't catch the difference, I changed the line: "* IN A 127.0.0.1" with "* IN CNAME dev.com.".

PS.: This is NOT a tutorial, so read the post  linked in the start to make this works as you expect, since there contains what more you need to configure.
