192.168.0.0/16. Answer C, 10.0.0.1, falls in this range, as does Answer D, 172.16.0.15.A, B. Neither of these IP addresses fall within any of the three blocks of address spacesassigned to private addressing. Remember, the three address blocks set aside and definedas private address space are as follows:

■

10.0.0.0 with a subnet mask of 255.0.0.0, or 10.0.0.0/8 This network is a pri-vate address space that has 24 host bits that can be used.

■

172.16.0.0 with a subnet mask of 255.240.0.0, or 172.16.0.0/12 This network isa private address space that has 20 host bits that can be used.This provides a range of16 class B network IDs from 172.0.0.0/16 through 172.31.0.0./16.

■

192.168.0.0 with a subnet mask of 255.255.0.0, 192.168.0.0./16 This network isa private address space that has 16 host bits that can be used.This provides a range of256 class C network IDs from 192.168.0.0/24 through 192.168.255.0/24.
