Enabling IPV6

DigitalOcean offers 16x free ipv6 addresses with each droplet.
This has instructions, also see the Official digitalocean ipv6 guide.

First, you'll need to fill in digitalocean's network config template:
(details on droplet page) 

# /etc/rc.conf

defaultrouter="${IPV4_DEFAULTROUTER}"
ipv6_defaultrouter="${IPV6_DEFAULTROUTER}"
ipv6_activate_all_interfaces="yes"

ifconfig_vtnet0="inet ${IPV4_ADDR} netmask ${NETMASK}"
ifconfig_vtnet0_ipv6="inet6 ${IPV6_ADDR} prefixlen 64"

If moving packets between network inferfaces, enable gateway for ipv6 

# /etc/rc.conf

# if moving packets between ifaces
gateway_enable="YES"
ipv6_gateway_enable="YES"

If you plan to use more than one of the 16 ipv6 addresses, create network interface aliases for them. 

# /etc/rc.conf

# create public ipv6 aliases
ifconfig_vtnet0_aliases="\
                      inet6 ${YOUR_DO_IPV6}:f002 prefixlen 64 \
                      inet6 ${YOUR_DO_IPV6}:f003 prefixlen 64 \
                      inet6 ${YOUR_DO_IPV6}:f004 prefixlen 64 \
                      inet6 ${YOUR_DO_IPV6}:f005 prefixlen 64 \
                      inet6 ${YOUR_DO_IPV6}:f006 prefixlen 64 \
                      inet6 ${YOUR_DO_IPV6}:f007 prefixlen 64 \
                      inet6 ${YOUR_DO_IPV6}:f008 prefixlen 64 \
                      inet6 ${YOUR_DO_IPV6}:f009 prefixlen 64 \
                      inet6 ${YOUR_DO_IPV6}:f00a prefixlen 64 \
                      inet6 ${YOUR_DO_IPV6}:f00b prefixlen 64 \
                      inet6 ${YOUR_DO_IPV6}:f00c prefixlen 64 \
                      inet6 ${YOUR_DO_IPV6}:f00d prefixlen 64 \
                      inet6 ${YOUR_DO_IPV6}:f00e prefixlen 64 \
                      inet6 ${YOUR_DO_IPV6}:f00f prefixlen 64"

If hosting regular non vnet jails, you may need to create ipv6 aliases for your jails. 

# /etc/rc.conf

# create private ipv4 clone addrs
cloned_interfaces="${cloned_interfaces} lo1"
ifconfig_lo1_aliases="\
                      inet 192.168.32.1/24 \
                      inet 192.168.32.2/24 \
                      inet 192.168.32.3/24 \
                      inet 192.168.32.4/24 \
                      inet 192.168.32.5/24 \
                      inet 192.168.32.6/24 \
                      inet 192.168.32.7/24 \
                      inet 192.168.32.8/24 \
                      inet 192.168.32.9/24 \
                      inet 192.168.32.10/24 \
                      inet 192.168.32.11/24 \
                      inet 192.168.32.12/24 \
                      inet 192.168.32.13/24 \
                      inet 192.168.32.14/24 \
                      inet 192.168.32.15/24"

Make sure your firewall allows expected traffic through ipv6 

sudo pfctl -sr  # examine rules

Finally, restart your network and test 

# restart networking
sudo service netif restart
sudo /etc/rc.d/routing restart
