Hi all,
So I’m trying to setup ipv6 for my droplet following this instruction.
I’ve enabled ipv6 in DO panel after the creation and added following lines to the /etc/networking/interfaces:
# The primary network interface
auto eth0
iface eth0 inet static
address Y.Y.Y.Y
netmask 255.255.224.0
gateway Y.Y.Y.1
up ip addr add 10.18.0.5/16 dev eth0
dns-nameservers 67.207.67.2 67.207.67.3
iface eth0 inet6 static
address 2a03:XXX:XXX:XXX:XXX:XXX:2001
netmask 64
gateway 2a03:XXX:XXX:XXX:XXX:1
autoconf 0
dns-nameservers 2001:4860:4860::8844 2001:4860:4860::8888 209.244.0.3
But after reboot system picks up only ipv4 settings and link-local ipv6 address
root@XXX:~# ip -6 a show dev eth0
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 state UP qlen 1000
inet6 fe80::8080:e2ff:fedb:ae11/64 scope link
valid_lft forever preferred_lft forever
At the same time, I can set up ipv6 manually using, say, ip command.
Can you please point what do I missing?

Ubuntu 18.04 has switched to netplan, the current guide hasn’t been updated yet. Follow this steps:
- (sudo) vim /etc/netplan/50-cloud-init.yaml
- In “addresses” section add
- your_ipv6_address/64
- Below “gateway4:…” section add a new section “gateway6: your_ipv6_gateway”
- In “nameservers” -> “addresses” section add
- 2001:4860:4860::8844
- 2001:4860:4860::8888
- 209.244.0.3
- (sudo) netplan apply
- ping6 2001:4860:4860::8888
That guide is outdated (for ubuntu, still works for debian)
