Enabling IPv6 and fixing “Bogus Host Name” warning

IONOS uses DHCPv6+rtsol to assign IP address and routing configuration for the IPv6.

1. Add ipv6 in the Ionos panel
2. pkg install dual-dhclient-daemon
3. Update /etc/rc.conf:

...
ifconfig_vtnet0="DHCP"
dhclient_program="/usr/local/sbin/dual-dhclient"
ipv6_activate_all_interfaces="YES"
ipv6_defaultrouter="fe80::1%vtnet0"
...

4. Update /etc/dhclient.conf:

...
interface "vtnet0" {
  ignore host-name;
}
...

5. service dhclient restart vtnet0
