>Description:
Google provides public IPv6 name servers. If you try to prepend them in the dhclient.conf, you get an error because it won't accept IPv6 addresses.

interface "em0"
{
    prepend domain-name-servers 2001:4860:4860::8888, 2001:4860:4860::8844;
}

# /etc/rc.d/dhclient restart em0
Stopping dhclient.
Starting dhclient.
value 2001 exceeds max (255) for precision.
/etc/dhclient.conf line 13: too few numbers.

This doesn't work either:

interface "em0"
{
    prepend dhcp6.name-servers 2001:4860:4860::8888;
}

# /etc/rc.d/dhclient restart em0
Stopping dhclient.
Starting dhclient.
/etc/dhclient.conf line 14: no vendor named dhcp6.
    prepend dhcp6.name-servers

>How-To-Repeat:
configure /etc/dhclient.conf like above and restart dhclient.
