B．From the Internet Assigned Numbers Authority (IANA)

参考答案和解析

正确答案：C
解析：Explanation:
Normally a small network will be assigned a number of IP addresses from their ISP, or in some cases, such as DSL and cable modem, a single dynamic IP address will be assigned by the ISP. Only very large networks requiring a large IP block (normally more than a /20) will register with IANA, RIPE, or ARIN (American Registry of Internet Numbers) to obtain their IP addresses.

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.
