Dear Colleagues, In January 2007, the 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 are published online each month at: http://www.ripe.net/info/stats/dns-lameness/ In October 2008, we sent out notifications to a small number of randomly selected server administrators. Replies to these messages indicated a need for further refinements to our probes and the interpretation of the results. Since then, we have made these improvements and fixed some bugs in our code. We now have better data and are ready to begin sending email alerts about lame delegations to name server operators. The email 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 We will begin sending small batches of email alerts from Thursday, 26 February 2009, using data collected over the month of February. This process will continue until all alerts have been sent out. The alerts will show which zone was checked and what error conditions were detected for its name servers. If you have any questions, please contact <dns-help@ripe.net>. Regards, Anand Buddhdev DNS Services Manager RIPE NCC
