Which two IP addresses are private-address-space hosts usable inside an enterprise? (Choose two.)

Private IP address ranges are reserved for use within private networks and are not routable on the public internet. These ranges are defined by RFC 1918. The three private IP address ranges are: 1. Class A: 10.0.0.0 to 10.255.255.255 2. Class B: 172.16.0.0 to 172.31.255.255 3. Class C: 192.168.0.0 to 192.168.255.255 10.172.76.200 falls within the Class A private range. 172.31.255.100 falls within the Class B private range. 12.17.1.20 is a public IP address. 172.15.2.250 is a public IP address because its second octet (15) is outside the 16-31 range for Class B private addresses. 192.169.32.10 is a public IP address because its second octet (169) is outside the 168 range for Class C private addresses.
