Refer to the following document for JPNIC policy: "Policies for Address Space Management in JPNIC" Address space assigned to members is used to perform address assignment work delegated by JPNIC. Therefore, note the following points: ・JPNIC members are not permitted to consign other persons to assign addresses. A member who assigns addresses is responsible for assignment of the whole delegated space. ・The JPNIC member must carry out assignment work based on the address assignment rules set by JPNIC and make every effort to use addresses efficiently and aggregate routing information. ・Registration in the JPNIC database is part of the address assignment work. ・When assigning address space smaller than /24, it is necessary to set/manage/use the name server for reverse lookup. ・The contents of IP address assignment work consigned by JPNIC may be changed occasionally according to international assignment criterion. ・Addresses shall be assigned only to networks that are connected to the JPNIC member. ・When another JPNIC Member B comes between JPNIC Member A and the party receiving the assignment, Member B shall carry out the assignment work. ・Before carrying out assignment of addresses for a network that has multiple outside connections, thorough discussion should be held between the relevant network and possible JPNIC members, taking into account the aggregation of routing information. 2. IP address assignment criteria The JPNIC address assignment criteria is determined based on the contents of RFC2050 and the assignment criteria currently used in other registries including APNIC, which is the upper-level registry of JPNIC. The assignment criteria described here is regarded as appropriate by the current Internet community, and so may change in the future with trends or circumstances. Therefore, refer to the latest documentation at all times when performing assignment. "RFC2050 (INTERNET REGISTRY IP ALLOCATION GUIDELINES)" "Policies for Address Space Management in the Asia-Pacific Region" 2.1 Usage rate Usage rate is used as a criterion for IP address assignment. JPNIC defines the usage rate as shown below. Total number of addresses assigned to host, etc. from assigned space Usage rate = ------------------------------------------------- x 100 Size of assigned space - Number of subnets x 2 Example: Usage rate when /27 is assigned in the case that there are Network A (2 hosts), Network B (6 hosts) and Network C (9 hosts) (2 + 6 + 9) ------------ X 100 = Approx. 65% 32 - 3 * 2 2.2 Size of assigned IP address In order to assign a suitable size of address space, the network design plan of the JPNIC members themselves is referred to. The network design plan indicates the number of hosts to be connected just after assignment, 6 months after assignment, 1 year after assignment, the growth ratio estimated during those periods, and changes of network topology for possible improvement. Based on this network design plan, addresses are assigned considering the size of the address space so that the following condition on usage rate is met: Just after assignment Usage rate over 25% And Within a year after assignment Usage rate over 50% JPNIC considers the period within 3 months after assignment as "just after assignment." If there are too few hosts and the conditions are not met, assign addresses smaller than /24. In this case, measures for registering the name server or network information are required. Refer to "5. Assignment of address space smaller than /24" for details. It is not necessary for addresses to be assigned continuously. However, aggregation of routing information for the Internet as a whole must be considered. For example, it is possible to assign /23 and /30, and in this case the total number of addresses becomes 516 (512 + 4). Note that the usage rate should be calculated based on the total number of addresses in the assigned space. However, if an unnatural address usage state is found including cases where there is a subnet with an extremely low usage rate, or in the case of re-assignment to users within an extremely short period (assignment should be based on the forecast of 1 year), JPNIC may request further explanation in some cases. 2.3 Assignment in the past When you make a new assignment, do so based on the usage rate that includes all addresses already assigned. If you already receive provider-independent assignment by the registry (e.g. JPNIC, APNIC), it should be returned whenever possible and the JPNIC member must make a new assignment. The size of addresses assigned in this case shall comply with the criteria given in "2.2 Size of IP address assignment". However, if the JPNIC member does not announce routing information for an address already assigned to outside, the host that uses the address can be excluded from the number of hosts when calculating the usage rate. 2.4 Usage rate after assignment If it is found after assignment that the usage rate does not comply with the criteria, return it and try a new assignment. 2.5 When connection is lost Addresses assigned by JPNIC members to their own network must be returned to the JPNIC members themselves when connection to the Internet is lost. Please return the address within 3 months after connection is lost, in principle. The JPNIC member may use the returned address for new assignment. 3. Fee JPNIC collects a fee for an assignment that enlarges the address space, in principle. Refer to the following document for assignment targets and fee amounts: "IP Address Request Fee" 4. Flow of assignment work The flow of work carried out by the JPNIC member after being consigned to assignment work is shown below. 1) Checking the contents of assignment ・Inspect the contents of assignment. ・Estimate the actual IP address (space) based on "2.1 Usage rate" and "2.2 Size of IP address assignment" given above. ・Check for the presence of an application for IP address assignment evaluation. 2) IP address assignment work ・Carry out assignment after re-evaluating whether the estimated IP address (space) is adequate. 3) Assignment report to JPNIC ・Report the assignment to JPNIC; JPNIC will register the contents of the request in the database. 4) Checking JPNIC database registration information 5) Payment of fee Individual work is explained in detail in the following sections. 4.1 Checking the assignment contents 1) Inspection of assignment contents Inspect the request sent by the applicant for omissions or incorrect descriptions. It is difficult to assess whether any statements are false, but this should be considered where possible. 2) Estimation of IP address (space) The actual IP address (space) is estimated based on the request according to "2.1 Usage rate" and "2.2 Size of IP address assignment" given above. 3) Checking presence of IP address assignment evaluation request Verify that the size of the IP address (space) estimated based on the requested contents is suitable for evaluating IP addressassignment. If the size of the IP address space requested exceeds the assignment window size, IP address assignment must be evaluated byJPNIC. However, in the case of assignment to JPNIC members themselves, even if the size exceeds the assignment window size, an IP address assignment evaluation request is notnecessary, so carry out the assignment according to "4.2 IP address assignment work". Refer to the following document for details of the assignment window and JPNIC evaluation request: "JPNIC Evaluation Procedure for IP Address Assignment" 4.2 IP address assignment work Evaluate whether the estimated IP address (space) is appropriate again according to the standard of "2.1 Usage rate" and "2.2 Size of IP address assignment", and determine the size of IP address (space) to be assigned. Then, carry out assignment from the space consigned. 4.3 Assignment reporting to JPNIC When the JPNIC member issues a notification of addresses assigned to the network of the applicant, the assignment should be reported to JPNIC. For addresses that are assigned to the network of JPNIC members themselves, an assignment report (for JPNIC members) should also be made to JPNIC. Once the assignment of addresses has been reflected in the JPNIC database, the assignment work is considered as "completed". However, if the assignment of IP addresses is considered inappropriate upon receipt of the assignment report, JPNIC may prohibit assignment of the addresses. Note that if you make a request exceeding the assignment window, it will not be registered. Note that information on assignments reported to JPNIC must be disclosed. Use the request form shown below for reporting assignments to JPNIC. "IP Address Assignment Report Form (For User's Network)" Submit requests to JPNIC to the address shown below. Information is registered in the JPNIC database at the same time. Please describe the details in the IP Address Assignment Report Form and send it by E-mail. apply@ip.nic.ad.jp When you register based on the result of evaluation, be sure to fill in the evaluation No. of the registration form. Once a notice is received from apply@ip.nic.ad.jp stating that the form has been accepted and registration in the database completed, the work of the JPNIC member is complete. If the content of the form is deficient in some way, notification will be received from apply@ip.nic.ad.jp; make corrections till the form is accepted. 4.4 Checking JPNIC database registration information JPNIC database registration information can be checked as follows: Checking using whois: whois -h whois.nic.ad.jp XXX.XXX.XXX.XXX (IP Network Address) Searching using JPNIC's website at: http://www.nic.ad.jp/jp/db/index.html 4.5 Payment of fee JPNIC sends invoices for fees to the accountant registered in the membership information once every 2 months. The invoice is for the assignment described in "3. Fee". Refer to the following document for details of assignment targets and fee amounts: "IP Address Request Fee" 5. Assignment of address space smaller than /24 Notes regarding the assignment of address space smaller than /24 are given below. In the case of assignment of address space smaller than /24, be sure to register the network information after registration of the name server as shown below. 5.1 name server registration method JPNIC does not register name servers for address spaces smaller than /24. When an address space smaller than /24 is assigned, the JPNIC member must start a name server related to the address of /24 and register network information. The network name must be described as shown below in order to make it distinguishable from addresses assigned to JPNIC members themselves. ------------------------------------------------------------------------ b. [ネットワーク名] SUBA-NNN-MMM ------------------------------------------------------------------------ Here, NNN represents the JPNIC membership No. and MMM is an optional 3-digit character string determined among the members. 5.2 Network information registration method When you assign an address space smaller than /24, you need to register the network information for the assigned part in the JPNIC database. Register the IP network address in the registration form for normal network information in address prefix form as shown below. ------------------------------------------------------------------------ a. [IP ネットワークアドレス] 192.0.2.64/26 ------------------------------------------------------------------------ JPNIC does not register reverse look up servers of DNS for address spaces smaller than /24. Therefore, information regarding the name server can not be registered with network information for an address space smaller than this /24. 6. IP address return The JPNIC member must return IP addresses included in address space consigned according to the following document: "IP Address Return Application Process" 7. IP address renumbering When you wish to carry out returning and assignment at the same time due to a change of connection, etc., refer to the following documents and carry out the renumbering process: "IP Address Renumbering Application (For User's Network)" 8. Qualifications for making an IP address assignment report request Regarding the address assignment report, JPNIC will only accept assignment requests sent from the E-mail address registered in [DB registration] of the JPNIC member information, to which the address block is allocated. 9. Inquiries If an incorrect IP address is registered in the assignment report, report it to the contact shown below within 5 business days from the day on which the assignment report was completed. This will then be processed as an invalid report even after it has been registered in the database. Cancellation of a report after 5 business days from registration in the database will be charged. If there are any unclear points regarding the procedure, send mail to the following address. query@ip.nic.ad.jp End of document *Related documents* "IP Address Assignment Report Form (For User's Network)" (http://www.nic.ad.jp/en/regist/ip/translation/e-ip-addr-assign-user-form.html) "IP Address Allocation/Return Request Process (For JPNIC Members)" (http://www.nic.ad.jp/en/regist/ip/translation/e-ip-addr-alloc-process.html) "Policies for Address Space Management in JPNIC" (http://www.nic.ad.jp/en/regist/ip/translation/e-ip-addr-ipv4policy.html) "Policies for Address Space Management in the Asia-Pacific Region" (http://www.apnic.net/drafts/ipv4policy-draftfinal.html) "IP Address Request Fee" (http://www.nic.ad.jp/en/regist/ip/translation/e-ip-addr-fee.html) "JPNIC Evaluation Information for IP Address Assignment" (http://www.nic.ad.jp/en/regist/ip/translation/e-ip-addr-evaluation-process.html) "IP Address Assignment Report Form (For User's Network)" (http://www.nic.ad.jp/en/regist/ip/translation/e-ip-addr-assign-user-form.html) "IP Address Return Application Process" (http://www.nic.ad.jp/en/regist/ip/translation/e-ip-addr-return-process.html) "IP Address Renumbering Application (For User's Network)" (http://www.nic.ad.jp/en/regist/ip/translation/e-ip-addr-renumber-user-process.html)
