JPIRR Mirroring Policy

1. Status of This Document

JPIRR is an IRR server which is operated on a trial basis for the following purposes:

* To verify the significance of JPNIC setting up a public IRR server in Japan
* To propose the improvements of IRR environment

The operation of JPIRR is based on "JPNIC IRR (JPIRR) Operation Policies and User 
Guideline". For details, please refer to:

http://jpirr.nic.ad.jp/docs/JPIRR_Operation_Guide_en.txt

This document describes the types of mirroring as well as the details of operational 
policies of JPIRR's data proxy undefined in the above policy.

2. Types of Mirroring 

There are three major types of mirroring that JPIRR provides:

1) Distribution Mirroring
A mirroring that JPIRR distributes the IRR data of JPIRR source to other IRRs.
 
2) Collection Mirroring
A mirroring that JPIRR collects the IRR data from other IRRs.

3) Transfer Mirroring
A mirroring that JPIRR distributes the IRR data which is not JPIRR source to other IRRs.

3. Mirroring Policy

This section describes how JPIRR provides three types of mirroring mentioned above.
   
3.1 Distribution Mirroring

In Distribution Mirroring, any individual/organization is able to mirror the database by 
simply sending a request to JPIRR.

However, they are subject to the following conditions:

1) The data obtained by mirroring JPIRR should be limited within the 
individual/organization who accesses the data. However, the summarized data which 
does not identify the contents can be exempted from this limitation, given that the 
receiver seeks JPNIC for the permission to publish such data.   

2) JPNIC and the JPIRR operators shall not be responsible for any liabilities which may 
be caused by the mirroring of JPIRR or by the usage of its data.

3.2 Collection Mirroring  

In Collection Mirroring, the IRR operator of JPNIC decides the IRR server to mirror 
JPIRR, in order to collect appropriate IRR data.

Under the current operational policy for JPIRR, APNIC's IRR server is the single source 
of Collection Mirroring. Through this mirroring path, JPIRR collects many IRR 
information, such as APNIC, RIPE and RADB. This operational structure is based on 
our proposed mirroring model.

3.3 Transfer Mirroring

Transfer Mirroring provides other IRR's data which JPIRR holds via JPIRR server, 
excluding JPIRR's data. However, depending on the data types, some of them are not 
permitted to distribute. Therefore, these will be excluded during the transfer.

The conditions to receive a Transfer Mirroring are the same as ones of a Distribution 
Mirroring. However, the submission of a letter of intent for specific IRR source may be 
required on a request basis from the IRR owner.

4. Policy for JPIRR's Data Proxy

As exception of "3.1 Distribution Mirroring", this section defines "Policy for JPIRR's 
Data Proxy" in order to allow the mirroring policy proposed by JPNIC.

1) JPIRR allows providing its data via a proxy to an RIR/NIR's IRR service or an 
equivalent service.

2) The function of JPIRR's data proxy is to provide a lookup service of JPIRR data via 
other IRR servers specified by JPIRR.

3) In allowing users to mirror JPIRR data obtained through a proxy, one must oblige 
users to comply with the mirroring policy in 3.1.    

4) A JPIRR's data proxy and an IRR which receives JPIRR's data via an upstream proxy 
must not make any changes to JPIRR data.

5) JPNIC and the JPIRR operators shall not be responsible for any liabilities which may 
be caused by the usage of JPIRR's data proxy or its data.

6) When an IRR receives the data from a JPIRR's data proxy, they must inform an 
upstream proxy and JPIRR.
