IPv4-preferred was chosen as the default because difference of the loopback performance was large. I am a big fun to make FreeBSD IPv6-capable by default and prefer IPv6, but the concern was a possible negative impact for people who are using only IPv4. So, can we change it for 10.X now? We cannot use "whether IPv6 address is configured" because ::1 is always configured in GENERIC kernel. The change will be "IPv6-preferred if the kernel has INET6 support". Preferring IPv6 addresses has needed a knob in rc.conf even in 4.x: 4.X: ipv6_enable="YES" ipv6_ifconfig_em0="2001:db8::1 prefixlen 64" 9.X and later: ip6addrctl_policy="ipv6_prefer" ifconfig_em0_ipv6="inet6 2001:db8::1 prefixlen 64" and if we change the default to ipv6_prefer, ip6addrctl_policy= line will be unnecessary. -- Hiroki ----Security_Multipart(Fri_Aug__3_14_28_47_2012_667)-- Content-Type: application/pgp-signature Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (FreeBSD) iEYEABECAAYFAlAbYY8ACgkQTyzT2CeTzy2F6ACfR7DZj1cYRG19VMvXtv9Wj5g+ 9EEAnRJNtUGyL5dDDc/l5LIvBVFlxNUS =Temk -----END PGP SIGNATURE----- ----Security_Multipart(Fri_Aug__3_14_28_47_2012_667)----
