Sorry, Tor relays need an IPv4 address to join the network.<br>

Do you see this warning?<br>
<br>
[warn] Configured non-bridge only to listen on an IPv6 address.<br>
<br>
You could try setting up an IPv6-only bridge.<br>

<br>
If a relay doesn't know its IPv6 address, it can't tell the rest of the<br>
Tor network. So there's no point binding to all IPv6 addresses.<br>

No, IPv6-only relays won't work.<br>
Tor relays need to be able to connect to every other relay, and (at<br>
least for the foreseeable future) all relays have an IPv4 address.<br>
