[Apologies for duplicate emails] Dear Colleagues, The RIPE NCC has begun implementing the deprecation of the "rev-srv:" attribute. This was discussed on the DNS WG mailing list and at the RIPE 54 Meeting in Tallinn, Estonia, during the Database Working Group session. More details are available at: http://www.ripe.net/ripe/maillists/archives/dns-wg/2007/msg00090.html The plan suggested on the mailing list is being used and there are three stages: - Stage 1: Announcement - Stage 2: Syntax change - Stage 3: Clean-up The announcement was made to the Database Working Group mailing list on 27 April 2009. *Stage 2 has now been completed.* The RIPE NCC has removed the "rev-srv:" attribute from the RIPE RPSL syntax for INET(6)NUM objects. Any new objects created must not have this attribute included. If any objects that include this attribute are modified, then the "rev-srv:" attributes must be removed. If you wish to keep the information for documentation purposes, change the"rev-srv:" attributes into "remarks:" attributes. The "rev-srv:" attribute has also been removed from the list of inverse query options. Stage 3 is planned to be completed before RIPE 59. A further announcement will be made before the cleanup is performed. If you have any questions about this, please contact ripe-dbm@ripe.net. Regards, Denis Walker Business Analyst RIPE NCC
