Network ranges in users files

[Sophie Loewenthal]

Hi,

     I'dl ike to add some addresses into /etc/raddb/users

Currently I have this,
     DEFAULT NAS-IP-Address == 195.222.222.0, Pool-Name := vodafone-nas-m2m

But I should change this to,
195.232.191.50
195.232.191.51
195.232.191.52
195.232.191.53

Maybe I could use 195.232.191.52/29 allowing 195.232.191.49 - 
195.232.191.54

Would these ideas work?
   DEFAULT NAS-IP-Address ==  195.232.191.52/29, Pool-Name := 
vodafone-nas-m2m

Or,
   DEFAULT NAS-IP-Address ==  195.232.191.50, Pool-Name := vodafone-nas-m2m
DEFAULT NAS-IP-Address ==  195.232.191.51, Pool-Name := vodafone-nas-m2m
DEFAULT NAS-IP-Address ==  195.232.191.52, Pool-Name := vodafone-nas-m2m
DEFAULT NAS-IP-Address ==  195.232.191.53, Pool-Name := vodafone-nas-m2m

Kind regards,
Sophie
