what is the purpose of network 10.17.0.0/16 on eth0?

Posted on May 9, 2018

while configuring firewall rules for a new (ubuntu 18.04 in nyc3) droplet today, i noticed that the output of route (below) shows three networks instead of the normal two (public, private).

can anyone tell me why the network 10.17.0.0 exists in our droplets?

104.131.0.0 - public 10.132.0.0 - private 10.17.0.0 - ???
