### Expected Behavior
No Log Spam with udpWrite() and or overflow

### Actual Behavior

Will provide them later, if i'm on PC.

### Additional Information
As you can see on the Screenshot, the Config Assistant is showing the public IPv6, shouldn't it also show the local IPv6? And if you setup Adguard Home for the first time, you only have the option for one IP-Adress or all, but there's also no local IPv6 showing.

If i could, i would configure Adguard Home to only respond on IPv4 + IPv6 from local network, i don't want him to listen on public IPv6 😉

Hopefully this is no duplicate of an open issue.
