+# Network Configuration
+
+## IPv6 Configuration
+
+JVB supports IPv6 in dual-stack (IPv4 + IPv6) environments.
+To enable it, add the following to your `jvb.conf`:
+```hocon
+ice4j {
+  harvest {
+    use-ipv6 = true
+    use-link-local-addresses = false
+    mapping {
+      stun {
+        addresses = [ "your-stun-server:3478" ]
+      }
+      static-mappings = [
+        {
+          local-address = "YOUR_PRIVATE_IPV4"
+          public-address = "YOUR_PUBLIC_IPV4"
+        }
+      ]
+    }
+  }
+}
+```
+
+### Notes
+- Jitsi Web and the Videobridge can have different IPv6 addresses
+- When IPv6 is enabled, a UDP6 listener will open on port 10000
+
+### Verifying ICE Candidates
+To confirm correct candidates are advertised, enable verbose logging in `/etc/jitsi/videobridge/logging.properties`:
+```
+org.jitsi.videobridge.xmpp.XmppConnection.level=ALL
+```
+
+Then grep the logs for `SENT` to inspect the ICE candidates being sent.
