A. B. C. D. E. F.


The Internet Assigned Numbers Authority (IANA) is a department of the Internet Corporation for Assigned Names and Numbers (ICANN) that manages the allocation of Internet Protocol (IP) address space, domain name system (DNS) root zone management, and other Internet Protocol-related symbols and numbers.

The three IP resources that IANA is responsible for are:

A. IP address allocation: IANA is responsible for allocating globally unique IP addresses to regional Internet registries (RIRs), such as ARIN, RIPE, and APNIC. The RIRs then allocate IP addresses to Internet service providers (ISPs), organizations, and end-users within their respective regions.

D. Autonomous system number allocation: IANA is responsible for allocating unique Autonomous System (AS) numbers to RIRs, which then allocate them to ISPs and organizations within their respective regions. AS numbers are used to identify networks on the Internet and are an essential component of the Border Gateway Protocol (BGP).

E. Root zone management in DNS: IANA is responsible for managing the DNS root zone, which contains information about the top-level domains (TLDs) on the Internet. This includes adding, removing, or modifying TLDs, delegating responsibility for TLDs to other organizations, and maintaining the root zone file.

Option B (Detection of spoofed address) is not a responsibility of IANA. Detecting and preventing spoofed IP addresses is the responsibility of Internet service providers and network operators.

Option C (Criminal prosecution of hackers) is not a responsibility of IANA. Criminal prosecution of hackers falls under the jurisdiction of law enforcement agencies in various countries.

Option F (BGP protocol vulnerabilities) is not a responsibility of IANA. BGP protocol vulnerabilities are the responsibility of network operators and vendors who develop and implement BGP-based routing solutions.
