Below is the output of `ifconfig gif0` on my machine at home: | gif0: flags=3D8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1280 | tunnel inet 83.181.147.170 --> 193.109.122.244 | inet6 fe80::202:a5ff:fe58:4927%gif0 prefixlen 64 scopeid 0x7=20 | inet6 2001:7b8:310::1 --> 2001:7b8:2ff:a4::1 prefixlen 128=20 As far as I know, the latest FreeBSD releases show an error message when assigning an address with a non-128 prefixlen. --=20 Ed Schouten <ed@fxq.nl> WWW: http://g-rave.nl/ --arYKMy5bKB/hcRo6 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.3 (FreeBSD) iD8DBQFEXuwg52SDGA2eCwURAiqTAJ9mKqasKfUYn4z1IptYKqorsxgecACcClUl JrWdrEIxkttt/bAlCTFhMzc= =fHy7 -----END PGP SIGNATURE----- --arYKMy5bKB/hcRo6--
