I’m running asuswrt on my router and it has a section to configure DNS Over TLS (Strict Profile) of which I’ve added both Cleanbrowsing servers (ie. 18.104.22.168, 22.214.171.124) with host security-filter-dns.cleanbrowsing.org.
When I do a leak test from dnsleaktest.com with Chrome browser I get two servers:
126.96.36.199 dns-edge-usa-west-seattle.cleanbrowsing.org. Choopa, LLC Seattle, United States
188.8.131.52 None Packet Host Parsippany, United States
I was only expecting one… the first one. Is the second server part of cleanbrowsing?
I’ve also tried the same test on a stock Internet Explorer browser (which I never use) with no extensions and I get the same result.
PS> Asuswrt also has preconfigured dns-over-tls for quad9, opendns, etc. I’ve tried them all and dns leak test always returns 1 server for them. Not sure what is specific to cleanbrowsing to return 2 servers.
