All,
Is there any support for disabling lameness checks for reverse DNS?
1. It seems that they cause some annoyance to administrators.
My feeling is that they only cause annoyance to administrators if the checks are not working correctly, personally if I have lame reverse zones I would be very happy if the NCC ran a service that warned me.
2. As far as I know there has never been a study showing improvement for DNS users based on removing lameness in reverse DNS (or in any DNS).
I'm not aware of any study either but I think we are all aware that certain applications work much better if reverse DNS is setup and functioning correctly. If those applications no longer had a dependency on reverse dns working then I may find it easier to agree with your point of view.
These two things suggest to me that the pro-active lameness checks should be disabled, at least until it is shown that lameness actually causes problems.
As I remember there was a lot of support for this work around the time of the publication of ripe-400 and my feeling is that providing the checks are being done in a sensible way and they are documented that this support is still there. Brett
