+#### Better Caching of multiaddresses for providers in DHT servers
+
+Thanks to [probelab.io's RFM17.1](https://github.com/plprobelab/network-measurements/blob/master/results/rfm17.1-sharing-prs-with-multiaddresses.md) DHT servers will [now cache the addresses of content hosts for the lifetime of the provider record](https://github.com/libp2p/go-libp2p-kad-dht/commit/777160f164b8c187c534debd293157031e9f3a02).
+
+This means clients who resolve content from theses servers get a responses which include both peer id and multiaddresses.
+This allows to skip a second query which resolves the peerid to multiaddresses for stable enough peers.
+
+This will improve content fetching lantency in the network overtime as servers updates.
