NameSurfer 7.6.4.1


On the View page you can add, remove or change FusionLayer NameSurfer's view settings. For more information on views, please see the Views page which lists all the views in the database.

Each view has a name and is defined as a set of IP address ranges. Optionally, a view may have (hidden) comments.


Name
The name of the view, for example "external". It is advised to give meaningful names to DNS views, such as "external", "internal" or "company.com-internal".

IP address range(s) for this view(s)
A view is defined as a set of IP address ranges for the view. These ranges should contain IP addresses of the secondary servers responsible for a particular view.

Submit buttons
After entering new data for a view, click the OK button to perform the change. If you wish to remove a view, click the Remove button (not available when adding a view).


DNS query view matching rules

When serving DNS zones, an order of preference is used when searching for matching view for the requested zone. The order of preference is as follows:

  • If the request was signed with a TSIG key, look for data in a view that matches the key used to sign the request. If no match is found, return zone data from Default view if the zone exists there.

  • If the request was not signed, try to match the requestor IP address with that of the views, and return the zone data from the view that provides the best address ramge match. If the zone is not found from the best matching view, return the data from Default view if the zone exists there.

  • If there are two best matching views that both have the same address range, both views are checked for the zone and if only one contains the zone, return the data from that view. If both views contain the same zone name, an error message will be returned instead. If neither of the views match, the Default view is checked for a match.
