Real resolver verification
Am I using ScotNet DNS?
This test creates a one-use hostname and checks whether ScotNet's resolver-local authority receives the DNS query. It tests this browser's current DNS path—not merely whether JavaScript ran or the website loaded.
- One-use hostname
- Authoritative observation
- Three honest outcomes
- Short-lived evidence
Run the check
Check this browser's DNS path
Positive observations normally appear within a second or two. A reliable negative waits about six seconds. The resolver-local authority retains the token observation for no more than 15 minutes and does not store or publish the client source address.
What the result means
- Using ScotNet DNS
- The unique DNS query reached ScotNet's resolver-local verification authority.
- Not observed through ScotNet DNS
- The resolver-local authority did not see the token before the short test window ended.
- Unable to determine
- The local verification path or public fallback authority could not return a reliable answer.
Important limitations
A real test with a narrow claim
Browser-level encrypted DNS, a corporate proxy, VPN DNS, captive portals and privacy relays can make the browser use a different resolver from the operating system. A positive result proves this browser's test query used ScotNet DNS at that moment. It is not a claim that every application or future query is protected.
