Are you sure you are setting a private auto generated address that Ubuntu changes so that you can’t be tracked? Thanks, John C.

Hi,

I'm running a non-exit relay on a home British Telecom broadband connection (FTTC, 20Mb up/80Mb down).

Its IP addresses (IPV4 & IPV6) are allocated dynamically.

The IPV4 address can remain the same for weeks. However the IPV6 address seems less stable and lasts no more than 2 or 3 days before changing.

A consquence of this is that Tor Metrics (atlas) shows a lot of downtime for the node.

When I see that the node is down I restart the (UBUNTU) NetworkManager although the host should pick up the new address eventually without doing that?

I would like to run a stable node with as little downtime as possible. Any suggestions on how I might improve things; in particular can I automate the checking and restart of the network/TOR whenever the IPV6 address changes? Do I really need to do this?

On that last point, I thought that TOR nodes handled more gracefully the issue of dynamic address changes? Is there any source of info on this for dynamic IPV6 addresses?

Thanks,

Quentin
