IPv6

got Docker running with Traefik as ingress Loadbalancer ?

Just enable IPv6 like this.

daemon.json

cat << EOF > /etc/docker/daemon.json
{
  "ipv6": true,
  "fixed-cidr-v6": "2001:db8:1::/64"
}
EOF

Restart Services

systemctl reload docker

Check Netstat

# netstat -tulpen |grep docker

IPv6 is fun, if you know how to handle it ! As a “sponsor LIR”, i got my own AS and a small /44 IP Space. So, as we all do “forward” DNS with our Domains, i’d like to have Reverse DNS as well. And as i don’t have a legacy IP Range, i like todo it with my v6 Space. Special thanks to Christian for his remote Hands/Tips. Appreciate it!

What’s my Public IP[4|6] Address from Cli ?

We all know the Situation when we’re working on some Maschines, locally or through ssh and asking ourself what ip address we get when reach out the internet.

My Dude “m2m” was so kind to wrote a litte Service years ago.

and you get the anwer, for ipv4 and ipv6 on one page. With IP, PTR, SAS and other information. Without AD, Tracking Cookies and all the other Shit.
