Small FAQ

What are the 'delegated nameservers' ?

When the checker talks about the delegated nameservers, it means one of two things. In the case of an existing zone, the delegated nameservers are the nameservers which are listed in the parent zone. In the case of a zone which is not yet inserted in the DNS tree, it means the nameservers which it has been given to check at.

What's all this about 'problem points' ?

Each problem which is found during the check has associated a certain number of points from 0 to 20. This number is displayed in brackets under the problem header. The number of points determines the classification of the problem as follows...

Error:20 or more points
Warning:1-19 points
Note:0 points

The final verdict after the check depends solely on the total number of points associated with the points that were generated. The classification into errors, warnings and notes is only intended to allow quick overview of the severity of a problem. It follows that a note does not affect the final outcome, but it only intended to be informational.

What are 'set' problems ?

The checker divides problems into two basic types: those that are specific to a particular nameserver and those that relate to all of the nameservers as a group. The latter are the set problems.

Example: a problem with the syntax of the serial number at nameserver X is reported together with all the other problems directly relating to nameserver X. In contrast, a difference in the serial number between nameserver X and nameserver Y is a problem with the whole set of nameservers.
