Behaviour

Tested over DNS over HTTPS every 15 minutes; the verdict is the majority of the last 24 hours. Last tested 2026-11-03 07:45 UTC.

DNSSEC validation

Validates

It checks DNSSEC signatures: a signed name comes back marked as verified (the AD bit), and a name with a deliberately broken signature is refused with SERVFAIL, so a forged answer would not reach you.

Its explanation for the broken name: EDE 6 (DNSSEC bogus)

Names that do not exist

Honest NXDOMAIN

A random name that cannot exist gets a plain NXDOMAIN, as it should. No redirection to search or advertising pages.

Client subnet (ECS)

Sends the client's subnet

It passes the first part of the client's address (a /24, here our server's) on to the domain's name servers, so CDNs can pick a server near you. Those name servers learn roughly where you are.

subnet 45.8.227.0/24

Filtering

Blocks the test name

It advertises blocking of phishing domains (on by default), and blocked the operator's own test name (internetbadguys.com).

Recent failed probes

No failed probes in the last 14 days.
