Which three IP resources is IANA responsible for? (Choose three.)
Click on the arrows to vote for the correct answerA. B. C. D. E. F.
The Internet Assigned Numbers Authority (IANA) is a department of the Internet Corporation for Assigned Names and Numbers (ICANN), responsible for allocating and managing several key Internet resources. These resources include IP addresses, autonomous system (AS) numbers, and the root zone of the Domain Name System (DNS).
Therefore, the three IP resources that IANA is responsible for are:
A. IP address allocation: IANA manages the allocation of IP addresses to the Regional Internet Registries (RIRs), which are responsible for distributing them to Internet Service Providers (ISPs) and other organizations in their respective regions. IANA also manages the allocation of special-use IP address blocks, such as private address space and multicast addresses.
D. Autonomous system number allocation: IANA is responsible for the allocation of AS numbers, which are used to identify and exchange routing information between autonomous systems in the Border Gateway Protocol (BGP). IANA assigns AS numbers to the RIRs, which in turn allocate them to ISPs and other organizations.
E. Root zone management in DNS: IANA is responsible for managing the root zone of the DNS, which contains the authoritative list of top-level domains (TLDs) such as .com, .org, and .net. IANA coordinates with the Internet Assigned Numbers Authority (IANA) functions operator, Public Technical Identifiers (PTI), to make changes to the root zone, such as adding or removing TLDs or changing their authoritative name servers.
The other options in the question, such as detection of spoofed address, criminal prosecution of hackers, and BGP protocol vulnerabilities, are not responsibilities of IANA. Detecting spoofed addresses is typically the responsibility of network operators, while criminal prosecution of hackers is the responsibility of law enforcement agencies. BGP protocol vulnerabilities are addressed by the Internet Engineering Task Force (IETF) and network equipment vendors.
