…ternal (#9281) This PR ensures that external addresses discovered by the identify protocol are not propagated to the litep2p backend if they are not global. This leads to a healthier DHT over time, since nodes will not advertise loopback / non-global addresses. We have seen various cases were loopback addresses were reported as external: ``` 2025-07-16 16:18:39.765 TRACE tokio-runtime-worker sub-libp2p::discovery: verify new external address: /ip4/127.0.0.1/tcp/30310/p2p/12D3KooWNw19ScMjzNGLnYYLQxWcM9EK9VYPbCq241araUGgbdLM 2025-07-16 16:18:39.765 INFO tokio-runtime-worker sub-libp2p: 🔍 Discovered new external address for our node: /ip4/127.0.0.1/tcp/30310/p2p/12D3KooWNw19ScMjzNGLnYYLQxWcM9EK9VYPbCq241araUGgbdLM ``` This PR takes into account the network config for `allow_non_global_addresses`.
