We are working on the rDNS issue and would like to ask anyone who is experiencing problems relating to this to send reports to dns-help@ripe.net with details about what DNS responses you are getting and what the difference is to what you are expecting. Updates will be posted to the service pages mentioned above as soon as they are available and we will send updates to the dns-wg@ripe.net and ncc-announce mailing lists as necessary.
