Named now uses NS lookups to perform QNAME minimisation. If one puts garbage in the NS<br>
records then they should expect lookups to fail. The NS records on both sides of a zone<br>
cut are supposed to be IDENTICAL. This is not a new requirement. It has been this way<br>
since the very beginning.<br>

Hello,<br>
At this point I am hoping that somebody might have a workaround so that we can exclude domains from this behavior if they are broken on the far end. Does anybody have a workaround for this?<br>
We are a small ISP and run BIND compiled from source. We currently run 9.16.x<br>
Every time we try to move forward with 9.18 customers start to complain that they are unable to reach certain websites. This includes banks, universities, and other organizations.<br>
I understand the goal is to get all DNS to RFC 6891, but from a practical standpoint, this isn’t working for customers, so we are prevented from upgrading either.<br>
