+ a systemctl restart networking. Had no effect.
ip a:
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast
state UP group default qlen 1000
link/ether b8:27:eb:d3:47:2d brd ff:ff:ff:ff:ff:ff
inet 192.168.71.12/24 brd 192.168.71.255 scope global eth0

inet 169.254.163.253/16 brd 169.254.255.255 scope global eth0

ip r:
pi@picnc:~ $ ip r
default dev eth0 proto kernel scope link src 169.254.163.253 metric 202
169.254.0.0/16 dev eth0 proto kernel scope link src 169.254.163.253
metric 202
192.168.71.0/24 dev eth0 proto kernel scope link src 192.168.71.12
So I'm still confused.
