IP address is a logical address, also known as a virtual address.

According to the regulations of ICANN, ICANN assigns some IP addresses to the regional Internet Registry (RIR), and these RIRs are responsible for the registration services in the region.

At present, there are five RIRs in the world: ARIN, RIPE, LACNIC, AfriNIC, APNIC,

(5) APNIC (Asia Pacific Network Information Center) is mainly responsible for the IP address allocation of countries in Asia and the Pacific.

In the Asia Pacific region, RIRs can also set up some IR, such as national IR (NIR) and regional IR (LIR), as shown in Figure 4-18. These IR can get Internet address resources from APNIC and then allocate them to their subordinates.
