I know for the NAT but there is some problems with SIP and NAT.
So I prefer use directly public IP with dom1.

Thanks for the answer.

Is it possible to attach directly one network card to DomU ?

yes, it's called PCI passthrough

I want my dom1 directly connected to Internet whereas Dom0 not because with
the bridge method, I have to use two public IP.

you can simply not give a public IP to the Dom0.  it doesn't need IP
to do the bridging.

or, you can give the public IP to Dom0, and use NAT+portforward to
DomU instead of bridging
