nas table

Hi people, I use freeradius 1.0.5 and am getting my nas information from nas table since several months ago. How ever, I realize I have to put DNS in this table because I have DDNS entries. Where must I put the DDNS in this table?? In ipddr I can not because is inet type and a primary key. What can I do?? _________________________________________________________________ ¿Estás pensando en cambiar de coche?
