Correct me if I am wrong but I believe that what you are trying to do is retrieve the FQDN (Fully Qualified Domain Name) using rDNS (Reverse Domain Name Service.

I note that you are trying to do reverse DNS on a private network i.e. 10.X.X.X. Unless you have configured reverse DNS for the private network, it is not going to work.

If, by chance, you are specifically trying to find the external URL for your present internet connection,
execute this:

Code:
curl jackson.io/url/
