That's not possible w/dns.he.net.  If you're using DHCP to assign addresses, you would need to run your own local name server and have DHCP send the updates to that one.

Dynamic update function works for hostnames added manually in dns.he.net control panel so they can be refreshed every time the IP changes from a certain client with a help of a DNS updater software.
What Im asking is, if there is a way with dns.he.net to automatically create a hostname every time an IPv6 is given to a client for some period of time. Like if one of my IP pool user got 2001:470:22ad:16d::1fad it would assign automatically "user-1fad.dyn.mydomain.com" when you lookup for the IP.

Check out the dynamic update function on the “dns.he.net” front web page.  That might cover what you want.

So I have configured plenty of devices with TunnelBroker from Ubiquity, Netgate to DD-WRT. Also I have delegated my IPv6 pools to "dnsX.he.net" and I have set up a subdomain "dyn.mydomain.com" of my main domain to be handled by "dnsX.he.net" by adding NS records for "dyn.mydomain.com" on my main domain.
So at this point everything is working, I can get IPv6 internet connection and I can manage the subdomain on my dns.he.net panel and manually create a hostname to my IPv6, however,  what Im trying to find out is how can I set up to automatically generate hostnames every time I get an IPv6 from my pool.
I know that this can be done with a DNS server that I can point my subdomain too, but what im trying to do is using the HE.net DNS server, I have already set my internal network to use them, both on IPv4 (74.82.42.42) and IPv6 (2001:470:20::2).

Why use the /64 if you have 64k worth of /64 in a /48?

Hello Tjeske.

I am in the windows version 1903.

Best regards.

Hi,
I have two routed subnets, standard /64 + /48. Generally it works, except routing between OpenVPN clients and /64 hosts. So the configuration looks like:
Server IPv6 Address:2001:470:xx:12e::1/64
Client IPv6 Address:2001:470:xx:12e::2/64
Routed /64:2001:470:yy:12e::/64
Routed /48:2001:470:aaaa::/48

eno1: 1.2.3.4/24
he-ipv6: 2001:470:yy:12e::2/64
tun0: 10.2.0.1/24 + 2001:470:aaaa:1::1/64
vmbr0: 192.168.101.1/24 + 2001:470:yy:12e::1

In the local network (192.168.101.0/24) I have some VMs and bare metal boxes running on dual ipv6+ipv4 stack. That works fine. On the VPN I have added IPv6 support to get it on my home aptop/desktop/rpi running behind IPv4 only network:

Code: [Select]

cd /etc/openvpn

server-ipv6 2001:470:aaaa:1::/64
push "route-ipv6 ::/0"
push "route-metric 2000"

Then routed two IPv6 networks:
ip route add 2001:470:aaaa::/64 via 2001:470:xx:12e::1
ip route add 2001:470:aaaa:1::/64 via 2001:470:xx:12e::1

The problem is that I can't access anything in the local network (on ipv6) using 2001:470:yy:12e::x network and vice versa.

Routing from the OpenVPN connected client to the internet (google):

Routing from the same OpenVPN connected client to the host in the server local network (2001:470:yy:12e::3):

Code: [Select]

  1.|-- 2001:470:aaaa:1::1         0.0%    10   45.2  45.1  44.4  46.0   0.0
  2.|-- ???                       100.0    10    0.0   0.0   0.0   0.0   0.0

Routing from the 2001:470:yy:12e::3 to the OpenVPN client:

Code: [Select]

  1.|-- 2001:470:yy:12e::1         0.0%    10    0.3   0.3   0.3   0.3   0.0
  2.|-- ???                       100.0    10    0.0   0.0   0.0   0.0   0.0

But any IPv6 enabled host in the internet like my other server outside the network can access IPv6 OpenVPN client without any problems. So I am assuming that the problem is with the routing.
Any idea, what I have missed?

1) configure tunnel on SOME device that will act as the IPv6 ROUTER. This can be windows, pi, the router itself, something else. Your choice.

If you decide to use Windows 10 as the tunnel endpoint, you can't use Spring Creators Update/1803. The v6v4tunnel implementation is broken in that release. <=1709 or >=1809 is fine.

My Berlin tunnel was/is often located in Czech Republic. There are mainly three big 3rd party providers of IPv6 geolocation. You can check them here: www.iplocation.net. It helps to manually report the wrong location to them. Usually takes them about 1-3 months to update their database.

Unfortunately, Facebook e.g. is a different story. They seem to use their own database/methods and therefor always report me to being in Berlin (I am actually closer to Prague, but still inside Germany).

thank you very much Cholzhauer.
