IPv6 with FreeBSD 8.1

[Ferruccio Zamuner]

Ciao,

I was trying to configure my host with IPv6.

I've verified:

1)
options         INET6                   # IPv6 communications protocols
exists in /usr/src/sys/amd64/conf/MYKERNEL, and it is.

2) in /etc/rc.conf:
ipv6_enable="YES"

to be enabled, and it is.

But:
> ping6 -c4 ::1
ping6: ai_family not supported

even if ifconfig output:
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384
         options=3<RXCSUM,TXCSUM>
         inet 127.0.0.1 netmask 0xffffff00
         inet6 ::1 prefixlen 128
         inet6 fe80::1 prefixlen 64 scopeid 0x2

I'm a IPv6 newbie, but I've not understood from what I've read until now 
what I've missed or where/what I did wrong configuring IPv6 on FreeBSD 8.1.


Can you please help me with links, hints or explains to fix it and get 
it running?

Here there is also sysctl output filtered by inet6.
