Like this:
lucid-nonsense:~:% ifconfig re0 inet6
re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=389b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_UCAST,WOL_MCAST,WOL_MAGIC>
inet6 fe80::e2cb:4eff:fe26:6481%re0 prefixlen 64 scopeid 0x1
inet6 2001:8b0:151:1:e2cb:4eff:fe26:6481 prefixlen 64
inet6 2001:8b0:151:1:: prefixlen 64 anycast
inet6 2001:8b0:151:1:3950:9ee6:9c6b:8a8b prefixlen 64
inet6 2001:8b0:151:1:3fd3:cd67:fafa:3d78 prefixlen 64
inet6 2001:8b0:151:1:78ea:429a:bbd9:f62f prefixlen 64
inet6 2001:8b0:151:1:d2f:23d1:314c:5e2e prefixlen 64
inet6 2001:8b0:151:1:57f9:9484:e8b0:12d1 prefixlen 128
IPv6 doesn't deal in netmasks per-se: just in the length of the network
prefix. (64 is typical. 48 also fairly common.)
