· 10.0.0.0 - 10.255.255.255 (10/8 prefix)
· 172.16.0.0 - 172.31.255.255 (172.16/12 prefix)

This range is not recommended for use as a private IP range for a VPC because it is a public IP address range assigned to the SoftLayer Technologies, Inc., a cloud computing infrastructure provider.
Private IP ranges are used to define the internal IP address space of a VPC. These IP addresses are not routable on the public internet and can only be used within the VPC. The ranges that are recommended for use as private IP ranges are:
These ranges have been reserved by the Internet Assigned Numbers Authority (IANA) for private network use and should not be used on the public internet.
It is important to use the correct private IP range for your VPC to avoid IP address conflicts and to ensure that your VPC can communicate with other resources on your network.
