How does APNIC work?
APNIC does not own IP addresses. Instead, it acts as an intermediary that receives allocations of IP address blocks from the Internet Assigned Numbers Authority (IANA), the global body responsible for managing the distribution of internet number resources. APNIC then allocates these IP address blocks to its members, which include internet service providers (ISPs), national internet registries (NIRs), network information centers (NICs), and various other organizations across the Asia Pacific region.
This allocation process is governed by well-defined policies designed to ensure the efficient, equitable, and sustainable distribution of internet resources. According to Dr. Kuo-Wei Wu, a prominent figure in internet governance, “The efficiency of regional registries like APNIC is critical to the global operation of the internet. By managing resources locally, APNIC helps ensure that infrastructure development is aligned with regional needs while maintaining the global internet’s interoperability.”
Dr. Wu further highlights the importance of APNIC’s transparent allocation process, stating, “The role of APNIC is not just about distributing addresses; it is about managing the foundation upon which the internet continues to grow. The careful regulation of these resources helps avoid fragmentation and promotes collaboration within the region.”
These expert insights reflect the vital role of APNIC in ensuring the region’s internet infrastructure can expand sustainably, supporting a growing number of users and technologies while maintaining global connectivity standards.

APNIC’s key functions
While APNIC’s primary role is to allocate IP addresses and ASNs, its functions extend far beyond this basic task. Let’s take a look at the key responsibilities that APNIC undertakes to ensure the smooth functioning of the internet in the Asia Pacific region.
1. IPv4 and IPv6 allocation
One of APNIC’s most critical functions is the allocation of both IPv4 and IPv6 addresses. With the global depletion of IPv4 addresses, this task has become increasingly complex and vital for the continued expansion of the internet.
- IPv4 Allocation: The IPv4 address space, which has been in use for decades, is gradually running out due to the increasing number of internet-connected devices. APNIC plays a crucial role in managing this dwindling resource by allocating smaller IPv4 address blocks to network operators, ensuring that the transition to IPv6 is as smooth as possible.
- IPv6 Allocation: IPv6 is the next generation of internet addressing, designed to overcome the limitations of IPv4. APNIC is actively promoting IPv6 adoption and supporting network operators in transitioning to this new protocol. IPv6 provides an almost infinite number of IP addresses, allowing for the continued growth of the internet in the Asia Pacific region and beyond.
2. Whois database administration
Another important function of APNIC is the administration of the Whois database. This publicly accessible database contains information about the ownership and allocation of IP addresses and ASNs. It is a critical tool for network operators, researchers, and law enforcement agencies to track and trace internet resources, ensuring that any misuse or abuse of the internet can be quickly identified and addressed.
The Whois database also helps ensure transparency in internet governance by making it easy for anyone to access information about IP address allocations.
3. Reverse DNS management
APNIC also manages reverse DNS (Domain Name System) for the IP addresses it allocates. Reverse DNS allows users to query an IP address and retrieve the associated domain name, a vital process for ensuring the smooth operation of the internet. This function plays a key role in network troubleshooting, email validation, and security functions such as spam prevention, where verifying the legitimacy of incoming communications is crucial.
Dr. Lixia Zhang, a recognized expert in internet infrastructure, points out that “Reverse DNS is a cornerstone for maintaining trust on the internet. By ensuring that IP addresses can be mapped back to their domain names, APNIC helps verify the authenticity of data exchanges, which is vital for cybersecurity.”
In a similar vein, Dr. William S. Davenport, a leading researcher in network security, underscores the importance of reverse DNS in combating malicious activity: “Effective reverse DNS management not only aids in troubleshooting but also acts as an important tool in detecting fraudulent IP addresses used for spam or other forms of cyberattack. APNIC’s role in overseeing this process adds an extra layer of trust and security to the Asia Pacific region’s internet infrastructure.”
