      BPF ingress map: iif nat64Prefix v6Addr -> v4Addr oif
        47 /64:ff9b::/96 /2a00:79e1:abc:6f02:4aac:17dd:b40e:8bcc -> /192.0.0.4 52
      BPF egress map: iif v4Addr -> v6Addr nat64Prefix oif
        52 /192.0.0.4 -> /2a00:79e1:abc:6f02:4aac:17dd:b40e:8bcc /64:ff9b::/96 47 ether

$ adb shell dumpsys netd
