IPv6 is designed to always use a correct prefix length and avoid using a /128 for aliases. Is there a problem with specifying a /80 address to ip6.addr if a box is on a /80 network? I know many people are using 2001:db8::1/80 + 2001:db8::2/128 on the same interface similar to 192.168.0.1/24 + 192.168.0.2/32. It certainly works, but the both should be /80.... -- Hiroki ----Security_Multipart(Mon_Dec__9_17_51_19_2013_503)-- Content-Type: application/pgp-signature Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.13 (FreeBSD) iEYEABECAAYFAlKlhIcACgkQTyzT2CeTzy3wRgCbBu4WPPvfOg8c/bWpaYPug2e7 ne4AnjdqYfniXkm3rFTjj4ySHGUX/aTo =vPFj -----END PGP SIGNATURE----- ----Security_Multipart(Mon_Dec__9_17_51_19_2013_503)----
