Freeradius with IPV6

Hello, is it possible the combine IPV4 and IPV6 on the same freeradius server. Iam using redis as database, i would like to add new acct type called Start-IPV6 on the rediswho conf file and on rediswho.c when the acct request comes with Framed-IPV6-address i will use the conf section of Start-IPV6 instead of Start Section, is this configuration possible to do? Thanks in advance Bassem
