+
+The bananapi does currently assign random mac addresses to its ethnernet nic,
+which is bad if you want to assign static dhcp leases. To solve this issue just
+create the following udev rule:
+
+``` plain /etc/udev/rules.d/75-static-mac
+ACTION=="add", SUBSYSTEM=="net", ATTR{dev_id}=="0x0", RUN+="/usr/bin/ip link set dev %k address XX:XX:XX:XX:XX:XX"
+```
+
+Replace XX:XX:XX:XX:XX:XX with your current mac address:
+
+``` bash
+$ ip address
+1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN group
+default
+    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
+    inet 127.0.0.1/8 scope host lo
+    inet6 ::1/128 scope host
+       valid_lft forever preferred_lft forever
+2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP
+group default qlen 1000
+    link/ether 02:8a:03:43:02:2a brd ff:ff:ff:ff:ff:ff
+    inet 192.168.1.56/24 brd 192.168.1.255 scope global eth0
+    inet6 fe80::8a:3ff:fe43:22a/64 scope link
+       valid_lft forever preferred_lft forever
+    inet6 fe80::9985:bd71:3b59:4875/64 scope link
+       valid_lft forever preferred_lft forever
+
+```
+
+which is `02:8a:03:43:02:2a` in my case.
