Potential DNS leakage?

Hey, I have noticed that when I run the traceroute command for a domain on my Linux system, my ISP's DNS servers show up. I was wondering if this indicates DNS leakage to my ISP?

  • Hello,

    I have the same question. I did a test with dnsleaktest.com and I'm surprised by the results. I saw the DNS resolver of my ISP first and then Nextdns. Is it normal ?

    Thanks
