configuring pg_hba.conf file

hi friends

i have postgresql running on a linux box
we are around 25 developers in the local network using
it
for development

i wanted to know whether this is a way by which all
the users in my domain would get access to postgres
instead of entering all the ip addreses in the conf
file

some thing like
192.168.0.* 255.255.255.0

instead of specifying all the IP's like this

# TYPE  DATABASE    USER        IP-ADDRESS
IP-MASK           METHOD

local   all         all
             trust
host    all         all         127.0.0.1
255.255.255.255   trust
host    all         all         192.168.0.9
255.255.255.0   trust
host    all         all         192.168.0.4
255.255.255.0   trust


thanks in advance
Jagdish Rao
