    Hello :)

    In your /etc/named.conf file, look for:

    Code:
    view    "external" {
    What is the recursion value under this view? Please keep in mind that third-party tools are not always accurate. Have you tried checking on another utility or with the command line?

    Thank you.

    Hello

    Yes I have tested by another tools: Test for Open Resolvers

    It says closed, Addresses marked closed may not even be running a resolver.

    Right, based on the output you provided, it's simply an issue of the third-party test you used not showing accurate results.

    Thank you.
