Dear DatabaseMaster:<br>&nbsp;&nbsp;&nbsp;&nbsp; Thank you for reading my letter. I am a Ph.D student in Computer Science. Recently, I am working on how to validate the origins of BGP routes with the information exploited from RIRs. As well-known, the database of RIPE is famous for its accuracy. Thanks for the public access services of ripe database, I have built a prototype. However, some information of &quot;person&quot; objects that can be got from <a href="ftp://www.ripe.net/">ftp://www.ripe.net</a> has been taken out. I think you are trying to prevent spam. I do not intend to get the personal information of the person objects such as email, address and so on, but the relations among them are important for me. What I really want is the person objects&#39; admin-c, tech-c, mnt-by attributes. I have done many experiments, in which there is a high false positive rate with my prototype. It seems that it is difficult to bypass this barrier. So I beg for your help to get more information about person objects. Could you please tell me how to get the entire information? Thanks for your reading again. <br>
&nbsp;&nbsp;&nbsp;&nbsp; Best Wishes!<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Sincerely Xiaoqiang&nbsp; <a href="mailto:db-wg@ripe.net"></a>
