Dear Colleagues, In January 2007, RIPE Document ripe-400 was created to address lameness in the reverse DNS tree. This RIPE Document can be found online at: http://www.ripe.net/ripe/docs/ripe-400.html We have been monitoring name servers for some time now and statistics from the data gathered have been published online each month at: http://www.ripe.net/info/stats/dns-lameness/ We are now ready to start sending out notifications to the maintainers of these zones, alerting them to a problem. The e-mail messages will point to the DNS Lameness FAQs, which explain the possible problems and give some pointers to help solve them. The FAQs can be found online at: http://www.ripe.net/info/stats/dns-lameness/faq.html Initially, we will send less then 100 e-mails to various contacts. This number will increase over the following months until all maintainers with lame servers are contacted. Kind regards, Sjoerd Oostdijk DNS Services Group The RIPE NCC
