<h2>Management of IP Addresses</h2> <h3>Global IP Address Management</h3> <ul> <li> Currently, IP addresses are allocated and assigned in a hierarchical structure with <a href="http://www.iana.org/" class="external">Internet Assigned Numbers Authority (IANA)</a> at the top. </li> <li> IANA allocates address blocks to each Regional Internet Registry (RIR), then the RIRs further allocate those address blocks to National Internet Registries (NIR) or Local Internet Registries (LIR). </li> <li> An NIR allocates the address blocks to LIRs, which then assign the IP addresses to end-users. </li> </ul> <figure> <img src="/ja/ip/ipv4pool/img/admin.jpg" alt="Internet Registry" style="display: block; margin: auto; border-style: solid; border-width: 1px; width: auto;"> </figure> <p> As an NIR, JPNIC is entrusted to manage the IP addresses in Japan by the <a href="http://www.apnic.net/" class="external">Asia Pacific Network Information Centre (APNIC)</a>, which is the RIR in the Asia Pacific region. </p> <h3>IP Address Management in Japan</h3> <ul> <li> LIRs under JPNIC become IP Address Management Agents (hereafter, IP Agents), to whom JPNIC entrusts the IP address management business. Those IP Agents receive allocations from JPNIC, and assign IP addresses to end-users and their own networks. </li> <li> For more information: <a href="/en/ip/member/index.html">About IP Address
