Hello,
cellphone service providers have been abusing their generic DNS servers in the past. We should set a secure system-wide DNS to protect Volla users. DoT (DNS over TLS) should be activated by default. Consider use of Quad9 that is Secured w/ECS: Malware blocking, DNSSEC Validation, ECS enabled https://www.quad9.net/service/service-a ... d-features Its anycast (like 9.9.9.11) can be used world-wide and could/should be a standard-setting of all Volla devices.
