DNS quality[Link]

The DNS quality project is intended to monitor the quality of the .be zone per registrar and in total. As a registrar, you get access to the information concerning the domain names that are in your portfolio. This project focusses on the correctness of the name server configuration of your domains. For every domain in your portfolio the complete name server tree is walked and discrepancies between settings on the different levels are marked as warning or error depending on the severity of the discrepancy found.

The project intends to point out that there are still a lot of wrongly configured name servers and to give the registrar an insight of where the problems are located. We will do these extensive tests on a regular basis. This way we can monitor the quality in the long term hoping to improve the overall .be zone quality.


When clicking on the overview button you will find an overview of how many domain names have errors grouped by the number of errors. In the drop-down box you can also select to display statistics based on numbers including warnings or including warnings and notifications.

When rolling over the graph or the entries in the table, you will get more information on the topic linked to the part you are hovering over. The graph is split into parts linked to the number of errors (‘none’, 1, 2, 3 or ‘4 and more’). The table, which is sorted by the number of issues based on the selection you have made in the pull-down, gives you the number of domains grouped per amount of issues and the percentage of this group is compared to the number of domains in your portfolio.

When you click on one of the rows in the table, you will be directed to a web page with the domain names linked to the entry in the table you just clicked. Note that the graph is displayed using a flash plug-in. Install the appropriate plug-in if you do not see a graph being displayed.

Error frequency[Link]

Aside from statistics linked to domain names, there is also an overview of the most frequent configuration errors grouped per name server. The error frequency gives an overview of all the detected configuration errors linked to all the name servers used to serve the domains in your portfolio.

In this overview, you find a list of issues and their severity (Error, Warning or Notify), the number of name servers the issue is linked to, the relative portion of how many name servers are concerned, the number of domain names linked to these name servers that have this specific issue and the relative amount of domain names this constitutes.

Clicking on the name server number or the domain name number will bring you to the list of name servers or domain names respectively that are linked to this specific type of problem. Note that the domain names are grouped per letter, so you can find your way easily by selecting the appropriate letter.

If you follow the link to the list of name servers, you get a list of the domains linked to the specific issue. You can also directly use the ‘Name servers’ link.

Name servers[Link]

The next menu topic ‘Name servers’ brings up an overview of the top-50 name servers with the most issues. The name servers are ordered according to the total number of issues. Following the link of a name server will show you all the issues linked to the name server and the number of domains linked to the name server that have the specific issue.

Search domain results[Link]

Obviously, you can also look up any domain name in your portfolio and directly find the issues related to this domain name.

This is done by using the “Search domain results” button. You can specify the domain name and directly go to the appropriate page.

Error history[Link]

To determine the overall improvement of the domains in your portfolio, the ‘Error history’ page shows the evolution of the total number of issues concerning the domain names in portfolio. Therefore, the quality of the name server tree will be investigated periodically.

For every batch we run, there will be an error rate calculated. This way you can verify the effect of your infrastructure changes and the relative position to the average quality of the total .be zone.
