So while my patch for the DigitalOcean datasource fixes this usecase, the rendering of additional addresses actually breaks all the "if*" tools for secondary addresses and even IPv6. Consider:

root@utl-ubuntu-16-04-x64-50307:~# ifquery eth0
address: 138.197.91.79
gateway: 138.197.80.1
netmask: 255.255.240.0
broadcast: 138.197.95.255
root@utl-ubuntu-16-04-x64-50307:~# ip addr show eth0
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
