It works for ipv4, but not for ipv6

IPv4:

listen {
        type = auth
        #ipaddr = *
        ipaddr = 146.64.8.17
        port = 0
}

radius -X
...
Listening on authentication address 146.64.8.17 port 1812
Listening on authentication address :: port 1812
Listening on accounting address * port 1813
Listening on command file /var/run/radiusd/radiusd.sock
Listening on proxy address 146.64.8.17 port 1814
Ready to process requests.


IPv6:

listen {
        type = auth
        #ipaddr = *
        #ipv6addr = ::
        ipv6addr = 2001:4200:7000:1:21c:c0ff:fefb:dc67
        port = 0
}

radius -X
...
