Correct Answer: AC

Explanation:
Public addresses are publicly registered with the Internet Assigned Numbers Authority (IANA). Through a public IP address, you can access an Internet computer like a Web server.
The following statements are true of public IP addressing:
These addresses are publicly registered with the Internet Assigned Numbers Authority (IANA)
Through a public IP address, you can access another Internet computer, such as a Web server.
Other people on the Internet can obtain information about or access to your computer via a public IP address.
Public IP addresses are visible to the public.
The option stating that public IP addresses are publicly registered with the Internet Service Provider (ISP) is incorrect. Public IP addresses are registered with the Internet Assigned
Numbers Authority (IANA). Since 1998, InterNIC has been primarily responsible for allocating domain names and IP addresses under the governance of the Internet Corporation for
Assigned Names and Numbers (ICANN) body, a U.S. non-profit corporation that was created to oversee work performed by the Internet Assigned Numbers Authority (IANA).
The option stating that 10.0.0.0 to 10.255.255.255, 172.16.0.0 to 172.31.255.255, and 192.168.0.0 to 192.168.255.255 are the range of public IP addressing is incorrect. These ranges
belong to private IP addressing.
The option stating that private addresses are allocated by the IANA is incorrect. Private IP address are not managed, but are used by private organizations as they see fit.. The IANA is
governed by ICANN, and its primarily role is to allocate overseas global IP addresses from the pools of unallocated addresses, as well as DNS root zone management.
