#### 📢 libp2p announces all interface addresses
go-libp2p [v0.47.0](https://github.com/libp2p/go-libp2p/releases/tag/v0.47.0) includes a rewritten routing library ([`go-netroute`](https://github.com/libp2p/go-netroute/pull/64)) that fixes interop with VPN and WireGuard/Tailscale setups. A side effect: when listening on `0.0.0.0`, libp2p now returns addresses from all network interfaces instead of just the primary one ([go-libp2p#3460](https://github.com/libp2p/go-libp2p/issues/3460)).
This means easier connectivity and less manual configuration for most desktop, VPN, and self-hosted users. However, if you don't run with the [`server` profile](https://github.com/ipfs/kubo/blob/master/docs/config.md#server-profile) and have an empty [`Addresses.NoAnnounce`](https://github.com/ipfs/kubo/blob/master/docs/config.md#addressesnoannounce), your node may now announce internal addresses (e.g. Docker bridge `172.17.0.0/16` or Tailscale `100.64.0.0/10`) to the DHT. In the default setup, AutoNAT will probe and mark unreachable ones as offline and they won't be listed, but you can also filter them out explicitly.
To check what your node announces and filter out unwanted ranges:
```console
$ ipfs swarm addrs local
$ ipfs config --json Addresses.NoAnnounce '["/ip4/172.17.0.0/ipcidr/16"]'
```
The [`server` profile](https://github.com/ipfs/kubo/blob/master/docs/config.md#server-profile) already [filters common private ranges](https://github.com/ipfs/kubo/blob/master/config/profile.go#L24-L43) via `Addresses.NoAnnounce`.
