Selected Answer: D
For your VCN, Oracle recommends using the private IP address ranges specified in RFC 1918 (the RFC recommends 10.0/8 or 172.16/12 but Oracle doesn't support those sizes so use 10.0/16, 172.16/16, and 192.168/16). However, you can use a publicly routable range. https://docs.oracle.com/en-us/iaas/Content/Network/Concepts/overview.htm#IPv4
