Wildcard DNS records

[Chiesa, Stefano]

Hello all.
I manage several BIND 9.10.4-P8 servers with more of less 600 DNS zones.
Anyway I never used wildcard DNS record and I hope you can help me to understand.

The need is:
* I have a dns zone i.e.  example.com
* this zone will have an unknown number of sub domains, let's say   siteA.example.com, siteB.example.com, siteC.example.com with other record inside

I need to know if it is possible create an A record valid for all the sub domains, WWW for instance.

I thought that a record like this:
www.* IN A 1.2.3.4

could work and if I'd query   www.siteA.example.com   it would return   1.2.3.4 ... but it does not work.

Can you tell me if it is possible and how?

Thanks in advance.
Stefano.
