How to disable IPv6 at FreeBSD 9.x


add to /etc/rc.conf:

# IPv6 Networking
ipv6_network_interfaces="none"          # Default is auto
ipv6_activate_all_interfaces="NO"       # this is the default
ip6addrctl_enable="NO"                  # New way to disable IPv6 support
ip6addrctl_policy="ipv4_prefer"         # Use IPv4 instead of IPv6


more info here

  1. I don't want to disable IPv6. On the contrary, I want to adjust the precedence so that FreeBSD can prefer IPv6 instead of IPv4. Thanks for the information which directs me to ip6addrctl(8). Now my problem is solved perfectly.
