Is my DNS private in Portugal?
Standard DNS queries in Portugal are unencrypted and visible to your ISP. To protect your DNS privacy, use a provider that supports DNS-over-HTTPS (DoH) or DNS-over-TLS (DoT), such as Cloudflare, Quad9, or Mullvad DNS.
Which private DNS should I use in Portugal?
For maximum privacy in Portugal, use Mullvad DNS (no logging), Quad9 (no personal data logged), or Cloudflare (logs purged within 24h). All three support encrypted DNS and have global anycast networks for low latency.
