+# Avahi

+# Import notes
+
+To allow avahi to work, you will want to use it on your lan, with the macvtap driver. This is because avahi need to broadcast to your lan network.
+
+
+You may need to enable macvlan:
+```
+networks:
+  lan:
+    name: lan
+    driver: macvlan
+    driver_opts:
+      parent: enp1s0
+    ipam:
+      config:
+        # This should be your lan network
+        - subnet: 192.168.42.0/24
+          #- subnet: 192.168.42.144/28
+          # 192.168.42.145 -> 192.168.42.158
+          # 192.168.42.159

+        # This IP is outside my DNS range of my lan
+        ipv4_address: 192.168.42.100
+
+```
