Setting wild card IP's on postgres

Hi,

I am trying to allow application connections from all the hosts starting with IP addresses 10.4.***

Is adding the following line on pg_hba.conf is appropriate to do so?

host xuser xdatabase 10.4.*.*/32 password

Are would I have to set the IP address in a different way?

Thank You,
