第1题：

A．Addresses chosen by Ezonexam.com to communicate with the Internet.

B．Addresses that cannot be routed through the public Internet.

C．Addresses that can be routed through the public Internet.

D．A scheme to conserve public addresses.

E．Addresses licensed to enterprise or ISPs by an Internet registry organization.


正确答案：BD
解析：Explanation:
Private IP address space has been allocated via RFC 1918. This means the addresses are available for any use by anyone and therefore the same private IP addresses can be reused. However they are defined as not routable on the public Internet. They are used extensively in private networks due to the shortage of publicly registered IP address space and therefore network address translation is required to connect those networks to the Internet.
