Why is NextDNS resorting back to using Russian DNS servers - 37.252.254.39?

NextDNS fixed this issue overnight, yet the Russian DNS server - 37.252.254.39? has returned.

Why?

DNS Leak Test
Incorrect network configurations or faulty VPN/proxy software can lead to your device sending DNS requests directly to your ISP's server, potentially enabling ISPs or other third parties to monitor your online activity.

The DNS Leak Test is a tool used to determine which DNS servers your browser is using to resolve domain names. This test attempts to resolve 50 randomly generated domain names, of which 25 are IPv4-only and 25 are IPv6-only.

      Appears to be USA only for now; thank you... Im going to sleep, Happy Thanksgiving. Email me if you need anything.

      Been using OPNsense (attached config for NextDNS) for years with DNS over TLS; works wonderfully, allows me to filter as needed and I watch the Analytics constantly; noticed Russian Federation, since I block RU and CN, I became concerned.

      Ran https://browserleaks.com/dns and noticed the Russian DNS servers (masquerading as German?), so I reported it.

      Hope this helps,

      Lucas
